Experimental Studies of the Neutron-Deficient Gadolinium Isotopes. II. Gd145m
Abstract
The N=81 isomer Gd145m is characterized as having a half-life of 85 +/- 3 sec and an M4 isomeric transition of 721.4 +/- 0.4 keV. It also has a direct β+ɛ branch to the h112 state at 716.1 keV in Eu145. The intensity of this branch is 4.7% of the decay, implying a ft of 6.2. The M4 transition probability is calculated and compared with the trends among other isomeric transitions in this region.
