High-spin States in the Tz = -1/2 Nucleus 55Ni

Research output: Contribution to journalLetter


High-spin states of the isospin T-z = -1/2 nucleus Ni-55 have been identified for the first time by means of the reaction Si-28(Ar-36,2 alpha n) at 143 MeV beam energy. The GAMMASPHERE array together with ancillary detectors was used to detect gamma rays in coincidence with evaporated light particles. The level scheme of Ni-55 comprising four transitions is compared to its mirror partner Co-55 and shell-model calculations in the Sp shell.
