Identification of Near-spherical Multiparticle-hole States in 89Tc

Research output: Contribution to journalLetter


Excited states in the nucleus Tc-89 have been identified for the first time by measuring evaporated particle-gamma-gamma-coincidences via the fusion reaction Ni-58 + Ar-36 at 149 MeV. Nine gamma-ray transitions built upon the (9/2+) ground state have been found, reaching up to a probable spin of (33/2+) at 5.3MeV excitation energy. The levels are interpreted with the shell model.
