A Study of the Anomaly at Ec.m.=13.7 MeV in the 12C+16O System

The anomaly at 13.7 MeV (c.m.) in the 12 C+ 16 O system has been observed for the elastic scattering and the 12 C( 16 O, α) 24 Mg reaction but not for the inelastic scattering. The angular distributions of the elastic scattering showed backward angle anomaly (BAA) and an analysis by using the parity-dependent optical potential model reproduces this BAA fairly well. A resonance analysis concerning this anomaly indicates that the most probable value of J π of this resonance is 8 + . A discussion of the properties of this resonance is given.

Statistical Analysis of Energy Dependence of the 20Ne(16O, 20Ne)16O and 20Ne(16O, 12C)24Mg Reactions

A statistical analysis has been performed on the excitation functions for the 20 Ne( 16 O, 20 Ne) 16 O and 20 Ne( 16 O, 12 C) 24 Mg reactions from E cm =22.8 MeV to 38.6 MeV at θ L =13°. Results of this analysis suggest a large direct component. It is concluded that four peaks in the deviation function for the 20 Ne( 16 O, 12 C) 24 Mg reaction is of nonstatistical origin.
