Angular distributions in the range 10-60Â° have been measured for the reaction Ca46(α,d)Sc48 at Eα=25 MeV. The lowest final states populated are those of odd angular momentum Jπ=1+,Â 3+,Â 5+,Â andÂ 7+ belonging to the configuration (νf72-1πf72). As expected, the even-J states Jπ=2+,Â 4+,Â andÂ 6+ of this configuration are only very weakly excited. Angular distributions for several additional states up to 4.2-MeV excitation in Sc48 were also measured. The cross sections for these higher states are an order of magnitude lower than would be estimated from normalizing the microscopic distorted-wave calculations to the low-lying states.
