Evidence for violation of the Gallagher-Moszkowski rules in154Pm
The existence of two radioactive species of154Pm (1.8 min ground state and 2.65 min isomer) is established. The Nilsson model configurations assigned to these states give evidence against the validity of the Gallagher-Moszkowski coupling rules in154Pm.
Isomeric states (T½ ≥ 10−10 s) listed according to increasing half-life
Values of some 700 half-lives of isomeric states, ranging from 10−10 seconds to 106 years, are presented in order of increasing half-life.
