“…In this theory, the T values of the typical photospallation products are well systematized by a parameter es = T/(AA/At), which represents the average kinetic energy carried off by an evaporated nucleon: the Es values are independent of AA/A t and the average es value is 16 _ 5 MeV. The proton results [14][15][16][17] are also shown in Fig. The es values are more than 50 MeV, implying the different production mechanism from typical spallation.…”

Recoil properties and yields of radionuclides formed in the photofission of 197Au and 2~ by bremsstrahlung of end-point energies (E0) from 300 to 1100 MeV have been investigated using the thick-target thick-catcher method. The kinetic energies T of the residual nuclei were deduced based on the two-step vector model and discussed by comparing with the reported results on protoninduced reactions as well as those on photospallation. The charge distribution was reproduced by a Gaussian function with the most probable charge Zp expressed by a linear function of the product mass number A and with the A-independent width FWHMcD. Based on the charge distribution pa-*) A A265 H. Haba et al. rameters, the symmetric mass yield distribution with the most probable mass Ap of 92 m.u. and the width FWHMMo of 39 m.u. was obtained for 197Au at E0 > 600 MeV. The Ap value for 2~ was larger by 4 m.u. than that for 197Au and the FWHMMD was smaller by 6 m.u. A comparison with the calculations using the Photon-induced Intranuclear Cascade Analysis 3 code combined with the Generalized Evaporation Model code (PICA3/GEM) was also performed. A266Czech.
