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