High resolution 16 OÑg*,p 2 pÖ experiment

The reaction 16 O(g*,p 2 p) was studied with high energy resolution in the region of the D resonance at the AmPS facility of NIKHEF. Photoproduction cross sections were extracted for 1p1/2 and 1p3/2 neutrons in 16 O and the resulting pion and proton angular distributions are compared to model calculations by Lee, Wright, and Bennhold. The proton angular distributions are well described by the nonlocal version of the model and allow one to extract rms radii and spectroscopic factors for the 1 p1/2 and 1p3/2 neutron shells. The same calculations are in fair agreement with the pion angular distributions.
