Production and decay properties of the lightest osmium isotopes

Briscoe, A. D.*; Smallcombe, J.; 他60名*

Physical Review C, 113(4), p.044317_1 - 044317_10, 2026/04

The production of $$^{159,160,161}$$Os and $$^{159,160,161}$$Re was investigated in experiments performed at the Accelerator Laboratory of the University of Jyvaskyla. New decay chains assigned to $$^{160}$$Os were identified at beam energies of 310 and 330 MeV. These findings are compared with previous studies claiming the observation of $$^{160}$$Os and $$^{156}$$W.

In the selenium isotopes various shape phenomena are present, in particular the emergence of a dominant oblate deformation in the most neutron-deficient isotopes has been observed. The scenario of shape coexisting oblate and prolate bands has been proposed across the isotopic chain, with the crossing point of such bands being located near $$^{70}$$Se, where no coexistence has yet been identified. To determine the presence or absence of any low-lying $$0^+$$ state in $$^{70}$$Se, confirm the level structure, and interpret the nuclear deformation with theoretical models. A combined internal conversion electron and $$gamma$$-ray spectroscopy study was undertaken with the SPICE and TIGRESS spectrometers at the TRIUMF-ISAC-II facility. Nuclear models were provided by the Generalised Triaxial Rotor Model (GTRM) and the collective Generalised Bohr Hamiltonian (GBH). Despite a comprehensive search, no evidence was found for the existence of a $$0^+$$ state below 2 MeV in $$^{70}$$Se. Significant discrepancies to the previously established positive parity level scheme were found. GBH calculations using UNEDF1 mass parameters were found to reproduce the revised low-lying level structure well. $$^{70}$$Se does not have a well defined axial shape. The 2$$_2^{+}$$ state at 1601 keV resembles a quasi-$$gamma$$ excitation rather than a member of a shape coexisting band; the presence of such a band is all but ruled out.
