Multidimensional stochastic treatment of fission dynamics

FUSTIPEN Colloquium
«Multidimensional stochastic treatment of fission dynamics »
May 24, 2013,  GANIL, Caen, France

Ever since the advent of fission about 75 years ago, it has been common to describe the phenomenon as a transport process in the multi-dimensional space of nuclear shapes. This Colloquium highlights the status of the Langevin framework and discusses its practical utility at both low and high excitations where special simplifications may be exploited to simplify the treatment.
Dr Jørgen Randrup from the Lawrence Berkeley Laboratory will discuss how the highly dissipative nature of the nuclear shape dynamics causes the fission process to resemble Brownian motion which in turn may be simulated by Metropolis walks in the multi-dimensional table of the potential energy of deformation.
Dr Pavel Nadtochy from the Omsk State University will focus on the Langevin transport description of high energy fission where shell effects are unimportant. The investigation of the fission fragment mass, energy, and angular distributions, fission time scales, and neutron multiplicities at different dissipation mechanism will be reported. Additional information can be found in the lecture program.
