M033500100011 (COMP) Energy spectra of photoneutrons from chromium M033500100012 are compared with calculations within the M033500100013 evaporation model. M033500100014 COMMENT The anisotropy of fast photoneutrons from chromium M033500100015 and lead has been measured as a function of M033500100016 bremsstrahlung energy in the region 22-32 MeV. In M033500100017 the case of chromium the anisotropy increases with M033500100018 energy. A possible explanation for this is advanced, M033500100019 and the implications of this explanation are M033500100020 compared with results from other nuclei.
