Abstract

Lu150 was produced via the 1p3n fusion-evaporation channel by bombarding a Rn96 target with a297MeV Ni58 beam, evaporation residues were analyzed using the fragment mass analyzer at Argonne National Laboratory. A new delay-line amplification system was used to make a new more precise measurement of proton decay from the isomeric state in Lu150 [Ep=1.286(6)MeV, t12=52.58.7+13μs]. In addition the half-life of the proton emitting ground state was measured to be 43(5) ms. Proton decay partial half-lives for both transitions are compared with theory. The isomeric transition is found to have a significantly smaller spectroscopic factor than the h112 ground state transition.
