Popis: NH 4 and ND 4 have been the subject of many studies, experimental and theoretical. Fuke et al. have recently recorded the photoionization cross-section at threshold for ND 4 revealing unusual behavior. Based on this observation, theoretical calculations, and comparison with isoelectronic sodium and related alkali atoms, the existence of a deep Cooper minimum slightly below the ionization threshold is postulated for the 3s- n p channel of the NH 4 radical and its ND 4 isotope.
