Isomers from intrinsic excitations in and
Abstract
We report that a six-quasiparticle isomer with T 1/2 = 57(2) ns has been established in the doubly-odd isotope 200Tl and its level scheme is significantly extended. Half-lives of previously reported isomers in 200Tl and 201,202Pb have been determined and revised values are reported in a few cases, with T 1/2 = 397(17) ns and 7.0(5) ns for the I π = 5 + and 7 - states in 200Tl, 52(2) ns for the 41/2 + level in 201Pb, and 93(4) ns for the 16 + state in 202Pb. Configurations for the isomers have been assigned and these predominantly involve intrinsic excitations of neutrons from the i 13/2 subshell. Lastly, the inferred transition rates for the decay of these isomers compare well with single-particle estimates attesting to their intrinsic character.
