The present review covers historical aspects and present status of quantum shells (QS) in nuclei and some other quantum systems. The relation of QS with various nuclear features (deformation, pairing, giant resonances etc) is outlined. QS in nuclei and atomic clusters are compared. Supershells in atomic clusters are briefly described. Further, the recent studies related with QS in nuclei are...
Heavy ion linac for nuclear physics.
T.Kulevoy
NRC “Kurchatov institute” – Kurchatov Complex of theoretical and experimental physics
The high intensity heavy ion linac is an attractive instrument for the nuclear investigation. The high energy linac can be effectively used for the rare isotope production (for example – FRIB facility in MSU, USA and SPIRAL2 in GANIL, EU). The low energy...
Обсуждаются возможности использования современных ab initio подходов для описания различных характеристик легких ядер и ядерных реакций, индуцированных их столкновениями, границы этих возможностей и перспективы расширения этих границ.
Анализируется качество описания: спектров уровней энергии ядер; их размеров; электромагнитных моментов, вероятностей электромагнитных переходов между уровнями...

The Tagged Neutron Method (TNM), sometimes also called Associated Particle Technique consists in irradiating the object of study with fast neutrons with an energy of about 14 MeV, which are formed in the reaction d+t→α+n [1]. Neutron tagging is carried out by registering an alpha particle with a special position sensitive detector built into the neutron generator. The use of TNM in experiments...
The description of giant dipole (GDR) and monopole (GMR) resonance decay widths requires to trace the spreading of the highly excited, collective states along the hierarchy of particle-hole configurations with various degree of complexity. Naturally, one would expect that chaotic component of intrinsic structure of a finite many-body quantum system, exhibited in its spectral properties at low...
На основе компиляции [1] и файла ENSDF [2] создана новая база данных MagDa свойств ядерных состояний, для которых экспериментально определены магнитные моменты. Программа-интерфейс к этой базе данных позволяет делать выборки спектроскопической информации по различным параметрам, к которым относятся не только спин, энергия возбуждения, время жизни состояния, но и метод измерения и дата...
We start with an introduction to the theory of neutrino electromagnetic properties [1]. Then we consider experimental constraints on neutrino magnetic µν and electric dν moments, millicharge qν, charge radii <rν2> and anapole aν moments from the terrestrial experiments (the bounds from MUNU, TEXONO, GEMMA, Super-Kamiokande, Borexino, COHERENT, XENON1T, CONUS and the most recent bounds from ...
The Jiangmen Underground Neutrino Observatory (JUNO) represents a groundbreaking experiment currently under construction in China. Featuring a central detector with a diameter of 35.4 meters and containing 20 kilotons of liquid scintillator, which is read out by 17,612 large and 25,600 small Photomultiplier Tubes (PMTs), JUNO promises to deliver unprecedented statistics, high-energy resolution...
(Anti)neutrino luminosities and spectra arising from neutral- and charged-current weak reactions with a hot nucleus $^{56}$Fe are computed for pre-supernova conditions and compared with the contribution of thermal processes [1,2]. It is found that thermodynamically consistent consideration of thermal effects within the thermal quasiparticle random phase approximation produces a higher...
Today, one of the nuclear physics tasks of experiments at high-energy accelerator complexes is the study of the superdense nuclear matter phase diagram. It is assumed that during the formation of such matter there will be an increased yield of particles, which include heavy c- and s-quarks. Due to the short life-time of these particles for precise reconstruction of their decay vertex the new...
Thanks to the studies of the structure of matter at the beginning of the 20th century and subsequent significant discoveries in particle physics, today people have a powerful tool in the form of ionizing radiation both for scientific purposes and for various sectors of the world economy. The development of radiation technologies has allowed nuclear physics methods to become firmly entrenched...
The main idea of the MONUMENT project is carrying out experimental measurements of muon capture at several daughter candidates for 0n2β decay nuclei. Obtained results are used to check the nuclear matrix elements calculations. In addition, the nuclear structure and the information of the particle's angular correlations of that process could be clarified.
A new high-granular time-of-flight neutron detector HGND (High Granural Neutron Detector) is being developed and constructed in order to measure azimuthal neutron flow in nucleus-nucleus interactions within at the BM@N experiment (JINR). The detector consists of alternating layers of copper absorber plates and matrices of scintillation cells with individual light readout by silicon...
