In our previous publications [1–3] we discussed new original effect appeared at crossing of the metal foils by fission fragments (FFs). In the series of recent experiments we have compared the mass of the FF before (Mtt) and after (Mte) it passes the foil event by event. In the light of the obtained results, a FF from conventional binary fission is supposed to be born in the shape isomer state...

The study of 133Sn provides excellent conditions to investigate single-particle transitions relevant in the neutron-rich 132Sn region due to the simplicity of its nuclear structure. After many experimental activities employing one-neutron transfer reactions [1–4], traditional β-decay studies are an attractive technique to refine our knowledge on 133Sn. Since the positions of neutron...

The personal dosimetry of neutron exposure is one of the most difficult problems at workplaces. Behind the biological protection of nuclear physics facilities neutron radiation has continuous spectrum, spanning up to 11 orders in magnitude – from thermal up to several GeV. It is necessary the energy response function of personal dosimeter has to be as close as possible to the appropriate...

The mass-spectrometer MASHA designed for determination of the masses of superheavy elements. The system separates complete fusion reaction products induced by heavy ion beams. The polygraphene foil is used as a hot absorber of the reaction products. The results of a total efficiency and a separation time measurement of short-lived mercury and radon isotopes are presented. The total...

Very low energy neutrons (≈〖10〗^(-7) eV) called ultracold neutrons have a unique property – they can be stored in material or magnetic traps [1]. This gives a new opportunity to carry out experiments to study fundamental physics issues.
Most of UCN experiments are statistically limited. And we are today at a point at which fundemantal physics application require larger UCN intensities in...

Nuclides in the vicinity of double magicity have simple structure, possible to explain with the shell model. Then, the nuclei is described as well bounded core (built with magic number of nucleons) and walence nucleons. The excitation-energy spectrum is dominated by single particle extitations.
Understading how single particle states evolve as a function of neutron (or proton) number is of...

For all stages of low-background experiments starting from concept of the shields, modeling as well during the operation comprehensive knowledge of gamma and neutron ambient backgrounds at the experimental sites is between of the most important tasks. Many various types of detectors are usually applied for experimental studies and monitoring of these backgrounds. In general completely...

RIBs (Radioactive Ion Beams) research is an important direction in modern Nuclear Physics to
provide full coverage of the nuclear chart for nuclear-stable isotopes and to promote our knowledge to
the limits of nuclear structure existence. The information obtained in the RIB studies is indispensable to
resolve fundamental problems of nuclear physics (structure, reactions, origins of the...

Angular momentum dependencies of the parity splitting and electric dipole transitions in the alternating parity bands of heavy nuclei have been analyzed. It is shown that these dependencies can be treated in a universal way with a single parameter of critical angular momentum, which characterizes phase transition from octupole vibrations to the stable octupole deformation. Using the simple but...

Mechanism of simultaneous non-sequential four-neutron (4n) emission
(or ``true'' 4n-decay) has been considered in phenomenological
five-body approach.
This approach is analogous to the model of the direct decay to the continuum often
applied to 2n- and 2p-decays.
It is demonstrated that 4n-decay fragments should have specific energy and
angular correlations reflecting strong spatial...

Thermal effects on the electron capture and beta-decays rates are studied for 56Ni embedded in dense and hot matter of the collapsing core of a massive star. The influence of temperature on the strength distributions of GT transitions is considered in the framework of the Skyrme-TQRPA model. It is shown that thermal effects make possible negative- and low-energy GT transitions which are Pauli...

Representing extreme nuclear matter asymmetry 10He nucleus is attracted a lot of attention. Despite a long story of trying to research this unbound system, there are still many contradictions in obtained results. Partly it is connected with a difficult recognition of broad states in the continuum.
In recent experimental research, the spectrum of low-lying states in the 10He was populated in...

This work is devoted to a theoretical study of the Coulomb breakup of halo nuclei in a quantum mechanical approach. Exotic nuclei are the subject of intensive experimental and theoretical research. Coulomb breakup are relevant for interpretation and planning of experiments in radioactive beams.
The 11Be nucleus is regarded as a neutron halo consisting of 10Be core and one neutron. Energy...
