Abstract
The level structure of has been investigated using both stripping and pickup reactions. The and reactions permit the identification of a series of doublets arising from the coupling of a proton in the , , , , and single-particle states with a neutron hole in the shell. The and reactions populate the multiplets arising from coupling of a neutron hole in the , , , , , and states with a proton in the shell. A detailed analysis shows that the total strength in each multiplet is close to that for the corresponding single-particle or single-hole transition on . In addition to the strong transitions leading to states of these multiplets, some relatively weak transitions are observed which provide a measure of the mixing of different configurations. The structure and purity of the particle-hole multiplets below about 3-MeV excitation is in good agreement with shell-model calculations.
