Photoproduction of 0--200-MeV pions from /sup 12/C and /sup 7/Li

Journal Article · · Phys. Rev. Lett.; (United States)

Total cross sections for /sup 12/C(..gamma..,..pi../sup -/)/sup 12/N and /sup 7/Li(..gamma..,..pi../sup -/)/sup 7/Be are evaluated in the impulse approximation, with use of the Blomqvist-Laget photoproduction operator and pion distorted waves. A peak at low energies and the falloff of the cross section with increasing energy are found to be consequences of the changing overlap of pion waves with nuclear transition densities.
