Shape change induced by g 9/2 rotational alignment in 84,86Mo

Abstract: Neutron-deficient Z ≈ N nuclei 84,86 Mo have been investigated using pairing-deformation self-consistent cranked shell model calculations up to spin I > 20 . Our calculations are in good agreement with the experimental data, indicating γ-soft triaxial shapes at low rotational frequency and well-deformed triaxial-oblate shapes at high rotational frequency for both nuclei. The shape change is due to the alignments of the g 9/2 protons and g 9/2 neutrons.shape change, cranked shell model, molybdenum

“…In light nuclei (e.g., 8 Be = 4 He ⊗ α or 20 Ne = 16 O ⊗ α) α-cluster states can be identified experimentally either by enhanced cross sections in α-transfer experiments like ( 6 Li,d) or by large reduced widths θ 2 α in α-induced reactions. In heavy nuclei the preformation factor P in α-decay can provide valuable information on α-clustering of the decaying parent nuclei.…”

“…It was concluded that the observed yrast band in 88 Ru exhibits a band crossing "that is significantly delayed compared with the expected bahavior of a rotating deformed nucleus in the presence of a normal isovector (T = 1) pairing field...in agreement with theoretical predictions for the presence of isoscalar neutron-proton pairing". But such an interpretation may also be affected by shape coexistence effects, and despite several detailed studies [3][4][5][6][7] a firm conclusion on the experimental verification of proton-neutron pairing could not yet be reached. The relevance of shape coexistence has also been pointed out in large-scale shell model calculations of heavy N = Z nuclei [8].…”
