Effect of potential-energy-model inaccuracies on predictions of fission-fragment mass distributions based on the Brownian shape-motion method
Background: Most actinide nuclides fission asymmetrically. A common explanation was that this division benefited from leading to fragments in the vicinity of the doubly magic 132Sn. It was tacitly assumed that lighter nuclides would all fission symmetrically because a similar situation could not occur there. However, a weakly asymmetric mass distribution was found for some preactinides at energies
