The cross sections of 110 radioactive nuclide with mass numbers 22 ≤ A ≤ 198 amu from the interaction of 2.2 GeV/nucleon deuterons from the Nuclotron of the Laboratory of High Energies (LHE), Joint Institute for Nuclear Research (JINR) at Dubna with a 197 Au target are investigated using induced activity method. The results including charge and mass distributions are parameterized in terms of 3-parameter equation in order to complete the real isobaric distribution. Using data from charge distribution total mass-yield distribution was obtained. The analysis of the mass-yield distribution allows to suppose existence of different channels of the interaction such as spallation, deep spallation, fission-like and multifragmentation processes.

The recoil properties of fragments produced by the interaction of 4.4 GeV deuteron with 197 Au target have been studied. New experimental data on recoil properties for 90 nuclei, varying from 24 Na to 198 Au, were obtained. The technique applied was the thick-target thick-catcher and induced activity method. The deuteron beam was obtained from the Nuclotron of the Laboratory of High Energies (LHE), Joint Institute for Nuclear Research (JINR), Dubna. The experimental data were analyzed on the basis of the standard two-step vector model formalism. From this analysis we could find evidence to support the existence of several different mechanisms, such as spallation, fission and fragmentation, in the reaction investigated. Fission contributed appreciably to the formation of products in the mass region of 65 ≤ A ≤ 120. The kinematic characteristics of residual nuclei formed in the present deuteron-induced reaction have been compared to those from proton-induced reactions with gold target.

The experimental measurement data on theˇne structure of beta-decay strength function S β (E) in spherical, transition, and deformed nuclei are analyzed. Modern high-resolution nuclear spectroscopy methods made it possible to identify the splitting of peaks in S β (E) for deformed nuclei. By analogy with splitting of the peak of E1 giant dipole resonance (GDR) in deformed nuclei, the peaks in S β (E) are split into two components from the axial nuclear deformation. In this report, theˇne structure of S β (E) is discussed. Splitting of the peaks connected with the oscillations of neutrons against protons (E1 GDR), of proton holes against neutrons (peaks in S β (E) of β + /EC-decay), and of protons against neutron holes (peaks in S β (E) of β − decay) is discussed.
