Recoil-decay tagging study of 205Fr
Abstract
The nucleus 205Fr has been studied through γ -ray and electron spectroscopy using the recoil-decay tagging
technique. The resulting level scheme presents a spherical structure built on the 9/2− ground state and a rotational
structure on top of a short-lived isomer. The isomer, with a spin and parity of 13/2+ and a half-life of 80(20) ns,
de-excites by an M2 transition directly to the 9/2− ground state. Another, longer-lived, isomer, with a half-life of
1.15(4) ms, has also been found and assigned a spin and parity of 1/2+. Transitions populating and de-exciting
this isomer have been observed as well.
