A general microscopic approach to describe properties of excited states in non-magic nuclei is formulated. It is based on the consistent use of the Green function method in Fermi systems with Cooper pairing. The main attention is paid to even-even nu

The ground-state properties of superfluid nuclear systems with ^1S_0 pairing are studied within a local energy-density functional (LEDF) approach. A new form of the LEDF is proposed with a volume part which fits the Friedman- Pandharipande and Wiring

An approach based on the local energy density functional method for describing the ground-state properties of superfluid nuclei is presented. A generalized variational principle is formulated which corresponds, in the weak pairing approximation, to a

The interpretation of the low-energy orbital magnetic-dipole excitations of nonspherical nuclei, commonly called scissors modes, is examined. Different models are reviewed, and with the help of the fluid dynamical model and microscopic results from d

We discuss experimental facts and theoretical models of the isovector M1 response in nuclei. The three isospin components ( T 2 = −1, 0, 1), orbital and spin components are identified and introduced by isospin decomposition of the nuclear M1 operat

A new form of effective density dependent pairing interaction with gradient term leading to the concentration of the pairing gap field in the outer part of the nuclear surface is suggested. Within the framework of the density functional method supple

The extension of the self-consistent energy-density functional method to non-spherical nuclei is briefly described. A comparison of the spherical and the non-spherical approach in lead nuclei is given and first results for the chain of strongly defor

We demonstrate that incorporating a density-dependent pairing-correlation term in the energy-density functional allows one to self-consistently reproduce the observed trends both in nuclear binding energies and in charge radii including odd-even stag
