Analysis of isotopic yield distributions in /sup 11/B- and /sup 22/Ne-induced fission of /sup 238/U. [Statistical model]
Physical Review C(1976)
摘要
First moments and variances of measured rubidium and cesium isotopic distributions in the fission of /sup 238/U by /sup 11/B(E/sub lab/ = 85 MeV) and /sup 22/Ne (E/sub lab/ = 132 and 162 MeV) are analyzed in the framework of the statistical model for nuclear fission and of evaporation theory. Excellent agreement with the data is obtained for /sup 11/B-induced fission, assuming a compound-nuclear mechanism. The comparatively large isotopic variance observed in /sup 22/Ne-induced fission can be explained if moderate contributions from fission following direct reactions are taken into account. (AIP)
