Abstract
The reaction O-16(gamma*, pi(-)p) was studied with high energy resolution i n the region of the Delta resonance at the AmPS facility of NIKHEF. Photopr oduction cross sections were extracted for 1p(1/2) and 1p(3/2) neutrons in O-16 and the resulting pion and proton angular distributions are compared t o model calculations by Lee, Wright, and Bennhold. The proton angular distr ibutions are well described by the nonlocal version of the model and allow one to extract rms radii and spectroscopic factors for the 1p(1/2) and 1p(3 /2) neutron shells. The same calculations are in fair agreement with the pi on angular distributions. [S0556-2813(98)05812-9].
