States in95Mo and99Mo populated in the (3He, ?) reaction

Abstract

Abstract. The (3He, a) reaction on 96M0 and l~176 targets has been studied at a bombarding energy of 18 MeV. The I, transfer assignments have been made on the basis of angular distribution patterns and on an analysis of the ratios of the experimental and theoretical cross-sections of (3He, a) and (d, t) reactions data leading to the same final states. New states are observed in 95Mo at 3 373 keV (9/2+); spin and parity assignments are made to levels in 99Mo at 1621 keV 7/2 + (9/2 +), 1778 keV (5/2-) and 2078 keV (11/2-).

Half-lives of levels in99Nb and99Mo

“…A calculation of the probability of the 7/2+~5/2 + transition in 99Mo in connection with the measured transition probability could provide' a further check of the model. In particular, this comparison would help to understand the structure of the 7/2 + level, the singleparticle nature of which is not yet clear [11,18].…”

Experimental study of the rearrangements of valence protons and neutrons amongst single-particle orbits during double- β decay in Mo100

“…Neutron addition has been performed on 100 Ru [40,41], although the neutron removal with the (p, d) reaction has not. Of these four targets, only 100 Mo has been studied in the ( 3 He,α) reaction [42], which is required to provide good matching for large angularmomentum transfer. Where data does exist in the literature, the experiments were performed at different times using different experimental techniques, different bombarding energies, different ranges of excitation energy and so on.…”
