Elastic and Inelastic Scattering of Alpha-Particles from Even Mass Molybdenum Isotopes

Abstract

Elastic and inelastic scattering of 30.87 MeV alpha-particles from 92,94,96,98,100 Mo nuclei were studied to determine relative values of β L for the first 2 + and 3 - states precisely. An optical model and DWBA analyses were made. Values of β L R for the 2 + and 3 - states are compared with those obtained by various reactions. The trend of variation of β L R value with regard to A agrees well for the 2 + state among various but some differences are found for the 3 - state. Values of β 3 /β 2 obtained by the present work are compared with those obtained by the inelastic proton scattering. It is found that the former are smaller than the latter as a whole.
