This offers a new approach to the study of previously unknown cores in the vicinity of the recently discovered island whose superheavy cores [1, 2]. A study of the 9Be cluster structure in the coincident experiment was started at the deuteron beam of the Skobeltsyn Institute of Nuclear Physics.

In the first study, we measured the absolute cross-sections of ICF and CF products using off-line gamma-ray spectrometry using 10.11B beams on 122.124Sn targets [2, 3]. 1(b)) – absent in the previous work using a CF reaction [4] but observed in the (n, J) process [5] – with spin confirmed by measuring the transition multipolarity for the first time.

The experimental search for the production of the heavy helium isotope 9He was carried out in the stopping reactions of π--meson absorption [1] in the radioactive target 14C.

Since the positions of neutron single-particle states in 133Sn were established and confirmed in many measurements [1-5], our focus shifts to single-hole states expected at higher excitation energies. Our experiment was carried out at the ISOLDE Decay Station, where excited states in 133Sn were investigated via the β-decay of 133In and complemented by studies of the βn-decay branch of 134In.

Thus, accurate theoretical predictions of the α-decay energy and half-lives are essential for experimental investigation of new elements. To determine the decay energy, it is necessary to estimate the masses of the initial and final nuclei.

NEUTRINO INTERACTION WITH THE Ga-Ge SYSTEM AND NUCLEAR RESONANCES

Registration and identification of the scattered reaction products was carried out with the ∆Е-E telescope of silicon semiconductor detectors [1]. The experimental angular distributions for the corresponding ground states (g.s.) were analyzed within the framework of the optical model, the coupled-channel approach, and the distorted-wave Born approximation. 9Be consisting of two bonded helium clusters (3He+ 6He) is significantly suppressed, while two-body configurations (n ​​+ 8Be) and (α + 5He) including unbonded 8Be and 5He are found to be more likely.

From the analysis of this data, the probabilities of cluster configurations n + 8Be and α + 5He were determined, which were 69% and 25%, respectively.

In this regard, new experimental data on cross sections of nuclear reactions open a new level of information support for basic (nuclear physics, nuclear astrophysics, new energy sources) and applied (medical use of artificial radioactive isotopes ). researches. The main objectives of the study were to obtain new data on deformation parameters. The parameters of the potentials were determined phenomenologically by fitting the calculated cross sections to the experimental data.

The character of the angular distributions of elastic and inelastic scattering is well described.

In the ICF reactions, part of the incident ion fuses with the target nucleus, while the remnant moves forward at the same speed as that of the projectile. Several models have been proposed, but none are capable of understanding the ICF data at energies | to be explained 4–7 MeV/n. The forward recoil range distributions (FRRD) of the residues have also been measured in a separate experiment using the recoil catcher technique, which is the most direct and irrefutable method to decipher the two competing processes.

The results of the present work have been used to develop systematics for incomplete fusion processes that may be useful for developing a theoretical model for ICF reactions at low energies.

EXPERIMENTAL INVESTIGATION OF ECR ION SOURCE PARAMETERS USING SHORT PULSE INJECTIONS OF HG AND NOBLE GAS LEAKS AT MASHA SETUP Vedeneev V.Yu.1, Rodin A.M.1, Krupa L.1,2, Chernysheva D.V. S.1,V.1,V.N. Gulyaeva A.V.1, Kamas D.3, Komarov A.B.1, Novoselov A.S.1,. A large extraction time of mercury makes it almost impossible to find and research mercury-like SHEs. An extraction time could be reduced by using different ion source chamber and transport line wall linings.

For those reasons, the extraction time and efficiency of the ECR ion source were measured at the MASHA installation, FLNR, using a short-time throttle “Parker”, capable of making injections with a duration of up to 2 ms, and compared with results collected with continuously calibrated leaks. .

The measurement of integral cross-sections was carried out by the activation method on the bremsstrahlung of the Skobeltsyn Institute of Nuclear Physics of the microtron of Lomonosov Moscow State University with a maximum electron energy of 55 MeV on targets from the natural isotopic composition of boron and beryllium. The integral cross sections were first studied for the filling of 7Be, both in the (γ,2n) reaction in beryllium and in boron reactions at the 55 MeV limit energy of the bremsstrahlung gamma ray. Moreover, it was previously claimed that the cross section of the (y,y') reaction intensely filling the isomeric state decreases when the (y,n) channel is opened.

The study of integrated cross-sections was carried out by the activation method on bremsstrahlung from the Skobeltsyn Institute of Nuclear Physics of the Lomonosov Moscow State University microtron with a 55 MeV maximum electron energy on hafnium targets with natural isotopic composition and enriched at 179Hf, 180Hf.

This fact makes small collisional systems interesting for research of other QGP evidence and jet quenching [7], in particular. Neutral pi- (π0) and eta-meson (η) production research provides an efficient tool for jet-quenching probes, as long as their yields can be measured in a large transverse momentum range with relatively small uncertainties. The meson yield suppression and RAA centrality dependence can be considered a signature of jet quenching in 3He + Au collisions.

Obtained results can be useful for additional parameter discrimination and further development of different jet-quenching effective models.

Production of light neutral mesons (such as π0, η, KS, ω) with large transverse momenta (pT) suffers from jet-quenching effect [9]: Meson yields are suppressed compared to yields in elementary p + p collisions. In this report we present results for π0, η, KS, ω nuclear modification factor (RAA) measurements at mid-rapidity in Cu + Au collisions at √sNN = 200 GeV/c and U + U collisions at √sNN = 192 GeV / c. Analysis performed with PHENIX spectrometer at RHIC, meson yield measured using PHENIX electromagnetic calorimeter.

In Cu + Au core collisions, the invariant meson yields are twofold suppressed compared to p + p core collisions.

I will review some of our recent results from theoretical initial studies of light nuclei in the coreless shell model (NCSM) as well as various recent developments of the NCSM approach. To improve the accuracy of NCSM predictions, various techniques are used to extrapolate NCSM results to an infinite base space example. One of the most promising techniques of this kind is based on deep learning with artificial neural networks.

We have also developed the SS-HORSE extension of NCSM which makes it possible to calculate the energies and widths of unbound nuclear resonant states.

The ratio AI / μ = A / g, μ is the magnetic moment of the nucleus, g - the gyromagnetic ratio, approximately holds in all isotopic chains. The anomalies are related to the Bohr-Weisskopf (BW) effect, which arises as a consequence of the finite distribution of magnetization over the core volume. Although the obtained radius values ​​turn out to be slightly different, depending on the model.

This is due to the contribution of higher multipole moments of the magnetization distribution [1].

Transition densities provide us with detailed information about the dynamics of the spatial distribution of matter in any finite quantum system. Unlike odd-even nuclei in which these quantities have been studied both analytically and numerically [1, 2], they remain unexplored in odd-A systems. We derived formulas for the transition densities in core-plus-particle models with different levels of refinement [3, 4] and evaluated the particle correlation effects using a schematic model.

The implied trends were verified against the experimental data on radii of cadmium isotopes [5].

Selenium was filled in a circular Teflon box and placed in the end cap of the HPGe detector. In these nuclei, as a consequence of the isospin invariance of the nuclear forces, isovector proton-neutron (pn) pairing is expected to coexist in an equal amount with proton-proton and neutron-neutron pairing. This boson architecture, which is clearly analogous to that of the Interacting Boson Model in its simplest formulation (IBM-1), has been used for an analysis of 28Si [8].

As a peculiarity, the potential energy surface of this core turns out to be that expected at the critical point of the phase transition of the IBM structural diagram.
