Abstract/Summary:
This thesis reports the measurement of cross section and analyzing power angular distribution of elastic and inelastic scattering of 180 MeV proton for ;The DWIA framework, in which most inelastic proton scattering observables are analyzed, has three ingredients, (1) NN-effective interaction, (2) transition density, and (3) distorted waves. The procedure used here to obtain effective NN-interaction empirically is that first suggested by J. J. Kelly. It models effective NN-interaction guided by the nuclear matter theory(G-matrix) and employs the local density approximation(LDA). By using the transitions, for which transition densities are known, it fits the inelastic observable to determine the parameters used to model the momentum transfer(q) and density(;The salient results are: (1) It is observed that, although the data base was increased by combining the ;It is clear that the results and the technique used to obtain effective NN-interaction shows that there is substantial potential to gain both qualitative and quantitative insight into how the interaction between two nucleons is modified within the nuclear medium. In particular, at low-q effective interaction is reduced and at high-q repulsion is enhanced compared to free interaction.;Using the empirical effective NN-interaction determined as described above, we investigated the potential of determining the neutron transition density for four normal parity transitions excited in ;The fitted neutron transition densities, for all four transitions, are compared with the proton transition densities, determined by electron inelastic scattering, and with those of the prediction of the shell model.
