The differential cross section, spin-flip probability amplitude, and asymmetry for the inelastic scattering of19�6 MeV protons to the 2+ state in 54Feat 1�409 MeV are analysed. The antisymmetrized distorted wave approximation is used to evaluate the scattering amplitudes in which the reaction mechanism is represented by a generalized core polarization model. Good fits are obtained to the differential cross section and spin-flip probability data. The exchange core polarization contributions are shown to be essential to obtain such fits. However, the asymmetry data cannot be fitted simultaneously, and this failure demonstrates the limitations of the current collective model representation of the core polarization process

The differential cross section for the inelastic scattering of 135 MeV protons leading to the9/2+ (9·5 MeV) state in 13C has been measured. Microscopic DWBA analyses show that the angular distribution is well described by a pure (or nearly pure) 1p3/2 to 1d5/2 neutron transition with a total angular momentum transfer of 4, a description which is consistent with the previously observed large asymmetry in inelastic π+ and π- scattering to this state.

Differential cross sections for elastic scattering and ionization in positron–argon collisions as a function of energy (40–150 eV) are reported at 60°. Of particular interest is the energy range 55–60 eV, where earlier measurements by the Detroit group found a drop in the elastic-scattering cross section of a factor of 2. This structure has been tentatively attributed to a cross channel-coupling effect with an open inelastic-scattering channel, most likely ionization. Our results indicate that ionization remains an important channel over the same energy range and only begins to decrease at an energy above 60 eV.

The differential cross section of electron inelastic scattering by nuclei followed byγradiation is calculated using the multipole decomposition of the hadronic currents and by taking into account the longitudinal polarization of the initial electron and the circular polarization of theγradiation. We performed the analysis of the angular and energy dependence of the degree of electron and photon polarization which can yield information on values of weak neutral currents parameters.

The study of the nuclear structure for the elements 12C, 40Ca, and 6Li has been performed in the momentum range from 0 to 0.8 GeV/c by using K+N phase shifts. An optical potential is used to calculate the elastic differential cross section and total cross section for K+ scattering from 12C, 40Ca, and 6Li. Comparison with previous experiments shows better results for the elements 6Li and 40Ca and fair agreement for the element 12C.
