Abstract
was produced via the fusion-evaporation channel by bombarding a target with a 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 [, ]. 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 ground state transition.
