Nuclides in the vicinity of double magicity have simple structure, which can be described with the shell model. The nuclei is treated like closed, well bounded core, built with magic number of nucleons, and walence nucleons. The excitation-energy spectrum is dominated by single particle extitations. Therefore, there is a great need of systematic investigation of the nuclear structure of the...

Beta decay of very neutron-rich nucleus 85Ge (Z=32, N=53) was studied at the Holifield Radioactive Ion Beam Facility at Oak Ridge National Laboratory. A high-purity beam of 85Ge was obtained by combining two-stage electromagnetic separation with ion-source chemistry. The partial level scheme with several new transitions in the daughter nucleus 85As was proposed for the first time. The...

The d(t,n)4He neutron production reaction model was created in Geant4 by reason of the work on the study of modern neutron generators properties. The study of the created model showed a discrepancy between the data on the specified reaction cross sections in Geant4 with the real values that are given by ENDF databases. It was also found that Geant4 tools do not allow to take into account the...

The helium-3 proportional counter employed as a neutron monitor, has components of single helium-3 counter and moderator (polyethylene, paraffin). The helium-3 in this detector is responsible for capturing thermal neutrons that produce tritium and protons in the working gas.

Characteristics of nuclei far from the stability line are of particular interest. The predictions of regular nuclear models that give similar results for stable isotopes can vary greatly with an increase of neutron excess.
