Abstract
A new isomer with a half-life of 0.48(2) ms was identified in the nuclide Hg-181, which was produced in the complete fusion reaction Ca-40 + Sm-144 -> Pb-184* at the velocity filter SHIP (GSI, Darmstadt). The isomeric state was tentatively assigned a spin-parity of 13/2(+). We propose that this isomer de-excites by a yet unobserved low-energy, strongly converted gamma-ray transition, followed by a newly identified cascade composed of a 90.3 keV M1 and a 71.4 keV E2 gamma-ray transition.
