摘要：
Photofission cross sections of Bi-209, U-238 and Th-232 are very different, both in magnitude and in their dependence on the incident photon energy. In fact, in the quasi-deuteron energy region, sigma(f) (Bi) < 10(-2)sigma(f)(U), with sigma(f)(Th) having intermediate values. Also sigma(f)(Bi) increases monotonically vs. E(gamma), while sigma(f)(U) and sigma(f)(Th) (above 75 MeV) are approximatively constant. We propose here a parametrization of photofission in the quasi-deuteron region, which fits, up to E(gamma) approximately m(pi) the photofission cross sections of these three nuclei.
