A new more precise measurement of the ground-state proton decay of is presented ms]. was produced via the fusion-evaporation channel by bombarding a target with 310 and 295 MeV beams. The proton decay rate is consistent with emission from a prolate deformed or Nilsson state. No evidence is found for a previously reported proton decay from a high spin isomer in An upper limit for the production cross section for proton decay of at a bombarding energy of 325 MeV was established.
