Angular and energy dispersion in neutron-rich nuclei by neutron evaporation: A Monte Carlo simulation

Abstract

  In this paper we present the results of a Monte Carlo simulation of the effects of neutronevaporation on the angular and energy dispersions in neutron-rich nuclei as a function of the massnumber A, the kinetic energy E and the number of emitted neutrons. We based our simulation on theassumption of an isotropic random distribution for the neutron emission angles in space and on aMaxwell-Boltzmann distribution for the kinetic energy of the evaporated neutrons. Our resultsconfirm large angular and energy dispersions for light, low-energy nuclei and for high neutronchannels.
