PT Journal AU Gottardo, Aea Gadea, A Algora, A TI New spectroscopic information on Tl-211,Tl-213: A changing structure beyond the N=126 shell closure SO Physical Review C JI Phys. Rev. C PY 2019 BP 054326 EP 7pp VL 99 IS 5 DI 10.1103/PhysRevC.99.054326 LA English AB The neutron-rich isotopes Tl-211,Tl-213, beyond the N = 126 shell closure, have been studied for the first time in isomer gamma-ray decay, exploiting the fragmentation of a primary uranium beam at the Fragment Separator-Rare Isotopes Investigation at GSI setup. The observed isomeric states in Tl-211,Tl-213 show a deviation from the seniority-like scheme of Tl-209. The possible interpretation of the data is discussed on the basis of energy-level systematics and shell-model calculations. ER
