The radiative pion capture in nuclei has been studied by sum rules techniques. Two simple sum rules for the radiative-capture rates from 1s and 2p orbits are given in terms of the mean photon momentum, the nuclear density and the wave function of the

Appropriate sum rules are shown to reproduce the results of microscopic calculations made in the random phase approximation for the soluble Hartree model with l -pole— l -pole interactions. This approach has the merit to avoid the problem of studyi

The various contributions to the deuteron bremsstrahlung-weighted photonuclear sum rule sigma/sub -1/ are analyzed. It is shown that the unretarded normal L = 1 sum rule is model independent and that retardation, higher multipoles, and interaction ef

The coupling between the isoscalar and isovector monopole resonances in Nnot =Z nuclei is considered in the framework of the random phase approximation. We find that the one-body operator F/sub 1/ = 2(..sigma../sub n/(Z/A)r/sup 2//sub n/-..sigma../su

The processes of production of nuclear fragments are discussed in the framework of a two stage - two regime model. In the first stage a piece of excited nuclear matter is created. Its excitation energy depends on the number of target-projectile nucle

We study the conditions at which multiple break-up of nuclei occurs during a collision. A minimal temperature of about 5 MeV seems to be necessary to produce multifragmentation. The average number of fragments produced is correlated with the average

Information contained in mass yield distributions produced in protons and heavy ions induced reactions has been analyzed with two model independent sum rules. The average number of fragments of different sizes produced in one collision has been extra
