Abstract

The variation of two-nucleon photoemission cross sections and photon asymmetries over kinematic ranges defined by typical detector acceptances is investigated. A Monte Carlo sampling technique, applied to theoretical calculations based on an unfactorized, distorted-wave approach, is used to obtain average cross sections and photon asymmetries. Comparisons are made with calculations evaluated at one central point per bin. Significant differences between the averaged calculations and the central values are observed for 12C(γ,np) cross sections, while for (γ,pp) the differences are much smaller. The averaged photon asymmetries for both reactions are consistent with central values.
