The pion yield produced by 16-GeV electrons in a 0.6 radiation length beryllium target was studied at laboratory angles of 0.2’ to 1. lo. The experimental yields are somewhat larger than those estimated using the Drell and p -diffraction models for pion photoproduction, and they do not appear to decrease at small angles as expected from the theoretical models.
