Title: /sup 40/Ca(. gamma. ,p/sub 0/)/sup 39/K reaction for E/sub. gamma. / = 100-300 MeV

Abstract

The differential cross section for the /sup 40/Ca(..gamma..,p/sub 0/) /sup 39/K process has been measured in the energy range E/sub ..gamma../ = 100-300 MeV at laboratory angles of 45/sup 0/, 90/sup 0/, and 135/sup 0/. The cross section for the (..gamma..,p) reaction leaving /sup 39/K in its ground state was extracted from the tip region of the proton spectra measured at a series of bremsstrahlung endpoint energies. The data are compared with a distorted-wave impulse-approximation calculation based on a direct, single-particle knockout mechanism.
