L007200100012 RAD-DET (59-PR-140,AR) L007200100013 DETECTOR (NAICR) 4x4 in. well-type NaI(Tl) crystal. L007200100014 CORRECTION Corrections due to sample nonuniformity were less L007200100015 than 4%. As measurements were performed at energies L007200100016 above the (g,2n) and (g,3n) thresholds, these L007200100017 reactions were measured separately to determine the L007200100018 appropriate corrections. Maximum correction was 1.5% L007200100019 at 65 MeV.
