Fission modes in fermium isotopes with Brownian shape-motion model

Nuclear Theory 2019-12-13 v1

Abstract

Fission-fragment mass and total-kinetic-energy distributions following fission of the fermium isotopes 256,258,260Fm^{256,258,260}\text{Fm} at low excitation energy have been calculated using the Brownian shape-motion model. A transition from asymmetric fission in 256Fm^{256}\text{Fm} to symmetric fission in 258Fm^{258}\text{Fm} is obtained. The total-kinetic-energy distributions for the three isotopes show radically different behaviour due to varying contributions from different fission modes, with a double-humped distribution for 258Fm^{258}\text{Fm}.
