摘要：

High-resolution measurements for the Ca-40(gamma,p)K-39 reaction have been performed at E(gamma) = 60 MeV. Five groups of states in the residual nucleus were identified. The angular cross sections for the 2s1/2 and the 1d3/2 hole state are reasonably well predicted in an RPA model. Both the shape and the magnitude of the angular cross sections of the remaining groups of states suggest the excitation of two-hole-one-particle states evidencing a two-body photoabsorption mechanism.
