The charge-exchange nuclear excitations for the isobars 48 Ca → 48 Sc , 90 Zr → 90 Nb and 208 Pb → 208 Bi are considered in the framework of the theory of finite Fermi systems by exactly taking into account the particle-hole continuum. The dist

Differential cross sections (mainly of p, n processes) for spin-isospin excitations in nuclei are reviewed and compared with theoretical predictions, particularly as obtained from the theory of finite Fermi systems.

The energy spectra of 6 He nuclei from the 90 Zr( 6 Li, 6 He) reaction at E 6 Li = 93 MeV have been measured over the angular range of 7 ° ⩽ θ lab ⩽ 20 °. The theoretical DWBA analysis of these spectra and angular distributions was performed e

It is shown that an essential decrease of the rate of the allowed β-decay to the excited 0+ states as compared with that to the ground state may be due to the spin-quadrupole residual interactions. The latter may be also responsible for the appearan

The properties of collective I π = 1 + ( K = 0 and 1) states in doubly even deformed nuclei are investigated in the framework of the Tamm-Dankoff (TDA) and random-phase (RPA) approximations. The Hamiltonian of the model includes the pairing and spin

The influence of the long-range effective forces on alpha decay to first Kπ = 0+ states of boundary nuclei 232U, 230Th and 228Th is analysed. It is shown that only the model with pairing, quadrupole and spin-quadrupole effective forces can describe

The spectroscopic factors for the two-particle transitions to the ground and excited 0 + states are studied in the model with pairing, quadrupole and spin-quadrupole forces. A qulaitative explanation of the observed cross-section ratios in the actini

A calculation of positive parity states in 161 Er and 163 Er, within the non-adiabatic rotational model, has been performed, taking the Coriolis coupling of seven Saxon-Woods potential orbitals into account. Two parameters, the rotational parameter h
