Half-life of the 830.2 keV isomer in $^{97}$Sr
Résumé
The half-life of the 830.2 keV isomeric state in $^{97}$Sr, for which very different values are reported in the literature, has been measured. The experiment performed at the LOHENGRIN fission-frgment separator consisted of two independent measurements. The two measurements provided consistent results. The weighted average value $T_{1/2}$ = 526(13) ns, supports the interpretation of the 830.2 keV state in $^{97}$Sr, as the 9/2+[404] neutron-hole configuration.
