Does deuteron-induced fission on actinide nuclei prevails over the breakup at low incident energies?

Abstract

An analysis of the ${}^{231}$Pa$(d,3n)$${}^{230}$U reaction excitation function at energies around the Coulomb barrier has taken into account the pre-equilibrium and compound-nucleus cross sections corrected for the deuteron-breakup decrease of the total reaction cross section, as well as the inelastic breakup enhancement. The analysis reveals the dominance of the deuteron breakup mechanism unlike a former assessment in this respect of the deuteron-induced fission process.
