“…Low-lying structures based on these configurations are also reported in 181−185 Hg but do not constitute the ground state in these nuclei [31][32][33] which have J π = 1/2 − in each case. In Figure 4(a) is shown the excitation energies, as a function of neutron number, for a few of the low-lying states common to many odd-A Hg nuclei.…”

The neutron-deficient nucleus 173 Hg has been studied following fusion-evaporation reactions. The observation of the decay of excited states via γ radiation are reported for the first time and a tentative level scheme is proposed. The proposed level scheme is discussed within the context of the systematics of neighboring neutron-deficient Hg nuclei. In addition to the γ-ray spectroscopy, the α decay of this nucleus has been measured yielding superior precision to earlier measurements.

“…The spectroscopy of the Hg isotopes [2,7,8] shows a nearly constant behavior of the energy of the yrast * Electronic address: p.sarriguren@csic.es states in the range A = 190 − 198, which are interpreted as members of a rotational band on top of a weakly deformed oblate ground state. For lighter isotopes, 0 + 2 excited states appear at low energies, decreasing in excitation energy up to A = 182.…”

Bulk and decay properties, including deformation energy curves, charge mean square radii, Gamow-Teller (GT) strength distributions, and β-decay half-lives, are studied in neutron-deficient even-even and odd-A Hg and Pt isotopes. The nuclear structure is described microscopically from deformed quasiparticle random-phase approximation calculations with residual interactions in both particle-hole and particle-particle channels, performed on top of a self-consistent deformed quasiparticle Skyrme Hartree-Fock basis. The observed sensitivity of the, not yet measured, GT strength distributions to deformation is proposed as an additional complementary signature of the nuclear shape. The β-decay half-lives resulting from these distributions are compared to experiment to demonstrate the ability of the method.

“…A high-spin 13/2+ isomer, analogous to those seen in the heavier Hg isotopes [15-1 7], has also been observed and assigned the oldute 13/2+ [606] configuration. The existence of multiple shapes is a unique feature of 179Hg when compared to the heavier odd-mass 181'183'185Hg isotopes [15][16][17]. We also found evidence for competing triaxial and prolate structures in the neighboring 175Pt (N = 97) isotope, whose properties match closely those of 17gHg, with the exception that the oblate minimum rises significantly in energy at Z = 78 and has not been observed experimentally.…”
