Isomeric 13/2$^+$ state in $^{201}$Fr
We have identified an isomeric state in $^{201}$Fr for which we propose a spin and parity of $13/2^+$, and interpret it as arising from the $\pi(i_{13/2})$ configuration. A half-life of 720(40) ns was measured, corresponding to $B(M2)=0.17(2)$ W.u., in good agreement with those of other $13/2^+ \to...

| description | We have identified an isomeric state in $^{201}$Fr for which we propose a spin and parity of $13/2^+$, and interpret it as arising from the $\pi(i_{13/2})$ configuration. A half-life of 720(40) ns was measured, corresponding to $B(M2)=0.17(2)$ W.u., in good agreement with those of other $13/2^+ \to 9/2^- [\pi (i_{13/2}) \to \pi(h_{9/2})]$ transitions observed in other nuclei in the region. The nuclei of interest were produced in a fusion-evaporation reaction and their decay properties were investigated using the GREAT spectrometer at the focal plane of the RITU gas-filled recoil separator. |
