K- and L-shell ionization cross sections of superheavy elements and fission probabilities of the actinides in micas by a few MeV protons

Abstract

K- and L-shell ionization cross sections for a number of superheavy elements have been calculated for incident proton energies of a few MeV. It is noted that the K-shell ionization probability for an incident energy of about 15 MeV is of the same order of magnitude as that for the L shell with about 5 MeV protons. In additions, should such superheavies exist in a monazite sample K X-rays from the fission fragments from the actinides might be a competing factor with the L X-rays of superheavy elements.
