The densities and form factors of the proton andthe Roper monopole excitedstate resonance are calculatedusing a relativistic three-quark model. Small currentquark masses are used with the three-body Dirac equation solved in hypercentralapproximation.

The effect of projectile shape on cross sections and momentum distributions of fragments from heavy ion reactions is studied. We propose a new approach that implements the underlying symmetries of each isotope with a few parameters directly in the de

Results are presented which have been obtained by combined analysis of experimental data on differential cross sections and polarisations of elastic scattering of protons from a 13C nucleus at energies of 13.5, 14.5, 16, 16.75 and 17.5 MeV. The analy

Within the analytic folding model analytic expressions are found for potentials in the system of interacting heavy ions. A simple parametrization is proposed for the distribution densities of matter in light nuclei calculated in the hyperspherical-fu

The complication effects in the highly-excited state structure (impurity of the complex configurations of the 2p2h type) of the (γ, n), (e, e′) and (Μ−, γ) nuclear reactions with the40Ca nucleus have been studied in terms of the ph-approximati

The interaction potential of heavy ions4He,6Li,12C and16O is constructed in the folding model. The density distribution of nuclear matter for these nuclei is calculated in the framework of the hyperspherical function method. For the calculation of th

The paper deals with the photonucleon energy spectra for two branches of the giant resonance (T ) on the basis of the microscopic theory of the pre-equilibrium decay. The first stage of the reaction is described by the wave function obtained by matri

The effect of coupling of the usual particle-hole states to particle-hole states built above a collective state on the decay characteristics and structure of a giant resonance with higher isospin (T>) has been estimated. Numerical calculations are ca

Consideration is given to the properties of light nuclei in the method of hyperspherical functions with central realistic potentials. In general, the following set of parameters can be described satisfactorily for the nuclei: binding energy, excitati
