O16(Li7,Be7)N16 reaction at 50 MeV

Abstract

The elastic scattering of Li7+O16 has been measured at ELi=50 MeV and fitted with an optical model potential. The O16(Li7,Be7)N16 reaction has been investigated at ELi=50 MeV. States and groups of states were observed up to 6.3 MeV excitation in the N16+Be7 system. Angular distributions for N16 in 2- 0.0 MeV, 3- 0.297 MeV, and 4- 6.17 MeV states with Be7 in its ground state (Be07), and for N16 in the 3- 0.297 MeV state with Be7 in its first excited state (Be17), have been compared with distorted-wave Born approximation calculations. The distorted-wave Born approximation form factors were calculated microscopically using central and tensor forces and realistic transition densities. The calculations fail to reproduce the cross sections. Show more
