Guo, C. Y., Zhang, W. Q., Huang, H. et al. (37 more authors) (2024) Spectroscopy of 187Tl: shape coexistence. European Physical Journal A : Hadrons and Nuclei. 165. ISSN 1434-601X
Abstract
The prompt and delayed $$\gamma $$-ray spectra of 187Tl was studied via the 142Nd(50Cr, 3p2n)187Tl fusion-evaporation reaction at a beam energy of 255 MeV. An enhanced level scheme of 187Tl was established. The collective bands with one-quasiparticle configurations from the $$2f_{7/2}$$, $$1h_{9/2}$$, $$1h_{11/2}$$and $$1i_{13/2}$$orbitals and high-lying structures with possible three-quasiparticle configurations are investigated in terms of the tilted axis cranking covariant density functional theory. At low excitation energy, the rotational bands with one-quasiparticle configurations reflect coexistence of three shapes: prolate, triaxial, and oblate. The possible shapes of two microsecond isomers at high excitation energy are proposed.
