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

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.

Comment on Excitation function for the radionuclide 46Sc produced in the irradiation of 45Sc with deuterons and 6He

We show that the model analysis of new measured (d,p), (d,t), (6He,5He), and (6He,4He) reaction cross sections at incident energies around the Coulomb barrier (J. Phys. G: Nucl. Part. Phys. 38 (2011) 035106) led to results that are not consistent with similar calculated and evaluated data. On the other hand, it should be corrected by taking into account the direct processes.
