PHOTOSPALLATION OF COMPLEX NUCLEI AT INTERMEDIATE ENERGIES .3. COMPARISON WITH PICA CALCULATION

Monte Carlo calculations based on the PICA (Photon-induced Intranuclea r Cascade Analysis) code by Gabriel and Alsmiller have been performed for bremsstrahlung-induced spallation of V-51, Co-59, Y-89, I-127, Cs- 133, La-139 and Au-197 at bremsstrahlung end-point energies of 200 - 4 00 MeV and compared with the experimental results reported in part I o f this series of work and others and with the empirical ones reported in part II. The gross features of the experimental and empirical mass and isotopic distributions were found to be reproduced by the PICA cod e qualitatively for lighter targets of mass = 51 - 89, but not for hea vier targets. The limitations of the reproducibility by the PICA code were examined. The total photoabsorption cross sections are also discu ssed.
