Proton radioactivity of {sup 117}La

Journal Article · · Physical Review C
A new more precise measurement of the ground-state proton decay of {sup 117}La is presented [E{sub p}=806(5) keV, t{sub 1/2,p}=26(3) ms]. {sup 117}La was produced via the p4n fusion-evaporation channel by bombarding a {sup 64}Zn target with 310 and 295 MeV {sup 58}Ni beams. The proton decay rate is consistent with emission from a prolate deformed 3/2{sup +} or 3/2{sup -} Nilsson state. No evidence is found for a previously reported proton decay from a high spin isomer in {sup 117}La. An upper limit for the production cross section for proton decay of {sup 116}La at a bombarding energy of 325 MeV was established.
