Coupled channels analysis ofF19+12

Abstract

Angular distributions for elastic and inelastic scattering of the F+ C system leading to the (g. s. ),~( 0.197 MeV),~(1.554 MeV), and s+ (2.780 MeV) states in F were calculated with a coupled channels (CC) method using cluster folding (CF) interactions based on a ' 0+t+' C three-body model at EL, ( C)=30 -60 MeV. The calculations reproduce well the experimental angular distributions for the elastic and inelastic scattering to the~and~states at all energies, although for the inelastic scattering to the~and 2 states the phases of the calculated angular distributions seem to be shifted slightly backward from the experimental ones. The calculations are compared with the CC calculations using Woods-Saxon interaction in order to investigate the effect of the shape of the interaction.PACS number(s): 25.70.8c
