Poster session (Experimental and theoretical studies of the properties of atomic nuclei)
- Egor Zemlin (Saint Petersburg State University, Russia)
Superheavy elements are of great interest from the point of view of fundamental nuclear physics. The most important task of this direction is not only the discovery of new elements, but also the synthesis of the maximum number of isotopes of each element, which makes it possible to consider the change in the physical properties of heavy nuclei both with a change in the number of protons and...
In the Hartree-Fock-Bogolyubov (HFB) approximation, assuming the axial symmetry of nuclei with Skyrme forces (SkM* and SLy4), we calculated the properties of Ra and Th isotopes with A = 218 – 230. These isotopes are currently intensively studied for the presence of octupole deformation in them. In addition, HFB calculations of the properties of Ra and Th isotopes were carried out in the...
About 60 years ago G. Condo [1] suggested a possible existence of long-lived states of pionic and kaonic helium atoms
($\pi^- \mathrm{He}^+$ and $K^- \mathrm{He}^+$) in order to explain that a some fraction (about 2%) of the negative mesons decays after the stopping in the helium target, contrary to the hydrogen target.
A direct experimental evidence of the similar states was obtained by...
As one of the methods for the experimental detection of the multicluster structure of atomic nuclei, the authors proposed a method for expanding the experimental angular distributions of differential cross sections for elastic diffraction scattering into multicluster components [1-2]. Within the framework of the diffraction theory and under the assumption of total absorption inside the...
One of the standard methods to construct the internuclear potential is the folding procedure. Consequently, the characteristics of the Coulomb barrier obtained by this procedure turn out to be sensitive to both the parametrization of the nucleon-nucleon interaction and the quality of the description of the nucleons distribution in nuclei [1,2]. In this report, the calculations are carried out...
In our previous papers, we extensively studied odd-odd nuclei adjacent to doubly
magical stable nuclide $^{208}$Pb, as well as to also doubly magical neutron excess
$^{132}$Sn. To date, some experimental information has emerged also about the
properties of such nuclei in the vicinity of an extremely neutron deficient and
also doubly magical $^{100}$Sn. In our calculations of odd-odd nuclei...
The ground states of ${}^{13,14}$C, ${}^{13,14}$N, ${}^{14}$O nuclei were studied in two complementary few-body models. In first model the studied isotopes were considered as cluster nuclei with following configurations: ${}^{13}$C ($3\alpha + n$ ), ${}^{14}$C ($3\alpha + 2n$), ${}^{13}$N ($3\alpha + p$), ${}^{14}$N ($3\alpha + n + p$), ${}^{14}$O ($3\alpha + 2p$). In second model the...
Experimental and calculated the $F_2(\theta_y)$ and $F_4(\theta_y)$ alignment angular dependences of the ${}^{16}O$ nucleus in the excited state $3^-$ (6.131 MeV), formed in the reactions ${}^{16}O(\alpha,\alpha)^{16}O$, ${}^{14}N(\alpha, d)^{16}O$, ${}^{15}N(\alpha, t)^{16}O$ and ${}^{19}F(p,\alpha)^{16}O$ at energies $E_\alpha = 30.3$ MeV and $E_p = 7.5$ MeV are presented. The orientation...
The database MASCA contains the evaluated atomic mass values of AME 2020 [1]. The program-interface to it allows getting the recommended values of atomic mass and nuclear binding energy for a given nuclide, as well as the calculated values of the energies of the main nuclear decays; the energies of proton and neutron separations; nuclear pairing energies; energy thresholds of nuclear reactions...
