Abstract

Elastic and inelastic scattering of 24.5 MeV protons by even isotopes of tin, ^{116, 118, 120}Sn and ^{122, 124}Sn, has been studied with an energy resolution better than 20 keV. Approximately 30 levels in each isotope have been resolved up to an excitation energy of 4 MeV. Elastic scattering angular distributions have been analysed to yield optical-model parameters and the inelastic scattering angular distributions have been analysed in the distorted wave Born approximation (DWBA) using collective form factors to determine l and β_l corresponding to a large number of the transitions observed. The systematics of the states of each J^π are discussed and the results are compared to recent theoretical calculations.
