Fission-fragment mass distributions from strongly damped shape evolution

NUCLEAR REACTIONS ²³⁹Pu(n, F)²⁴⁰Pu, E=8-14 MeV; ^234,236U(n, F)²³⁵U/²³⁶U, E=8-14 MeV; ²³⁴U(γ, F)²³⁴U, E=8-14 MeV; ^{222,224,226,228}Th(γ, F)²²²Th/²²⁴Th/²²⁶Th/²²⁸Th, E=8-14 MeV; calculated fission fragment mass and charge yields, comparison with experimental data. Random walks on a five-dimensional potential energy surface within the framework of the Smoluchowski equation of motion.

NUCLEAR STRUCTURE ^{222,224,226,228}Th, ²⁴⁰Pu; calculated fission fragment mass and charge distributions. ²²²Th; calculated contours of three shapes relevant to fission, and the most probable symmetric fragment division in ¹¹¹Rh isotope.
