Double core hole (DCH) states enclose two vacancies in the electronic K-shell of atoms and molecules. This object currently attracts close attention and DCHs might become a new tool for chemical analysis [1] and plasma diagnostics [2]. DCHs are efficiently created by high-brilliance X-ray free-electron lasers in double ionization by two sequentially absorbed $\gamma$-quanta [3]. On another...
Collisions of metastable antiprotonic helium atoms with the medium atoms induce, inter alia, transitions between hyperfine structure (HFS) states, as well as shifts and broadening of microwave M1 spectral lines. These effects were studied in the experiments with the low-temperature $^4\mathrm{He}$ [1,2] and $^3\mathrm{He}$ [3] targets, and were considered in the framework of the model...
The investigation of distribution of charge density of nuclei by means of electronic scattering have begun from Hofstadter work series [1–2]. Further many important works were made in this field [3–5]. Here I present specific models of charge distribution with symmetrized Fermi distribution in the center of nuclei and small perturbation on periphery used for fitting electron scattering data by...
On the basis of the Hartree-Fock-Bogolyubov (HFB) method with various versions of Skyrme forces we investigated the position of the neutron drip-line (NDL) of Ca isotopes with allowance for axial deformation of nuclei. For calculations of the properties of the ground state of even-even isotopes of Ca, we used computer code HFBTHO v2.00d [1] and our software package as in [2]. Our calculations...
Nowadays all the elements up to 118th are known due to success of experimental nuclear physics in new heavy element synthesis [1], however, not all the masses of new nuclides have been measured. In our work, the phenomenological approach based on local mass relations is implemented to predict masses of unknown isotopes. This approach is characterized by mathematical simplicity and accuracy...
The properties and mass distribution of the ultramagnetized atomic nuclei which arise in heavy-ion collisions and magnetar crusts, during Type II supernova explosions and neutron star mergers are analyzed. For the magnetic field strength range of 0.1–10 teratesla, the Zeeman effect leads to a linear nuclear magnetic response that can be described in terms of magnetic susceptibility [1]....
In $[1]$ we have investigated the cross sections of the $^{13}C(d,p \gamma)^{14}C(3^–$; 6.73 MeV) reaction at $E_d$ = 15.3 MeV. In this article the double-differential cross sections of the same reaction were measured for six proton emission angles on the SINP MSU 120-cm cyclotron. The angular correlation functions $W(θ_\gamma, \varphi_\gamma; θ_p)$ were measured at four planes of gamma-rays...
The problem of halo nuclei [1] in a detailed analysis of sizes and deformations in isotopic series reveals not abrupt behavior in the topology of nuclei, but a sequential continuous change in the structural nuclear parameters as they move away from the axis of the "Line of stability". This suggests the inevitable correlation of structural isotopic parameters with electromagnetic and purely...
