摘要：

High spin states in the N = 50 nucleus Tc-93 were populated and studied using the reaction Zn-66(P-31, 2p2n)Tc-93 at a beam energy of 115 MeV. Gamma ray intensities and gamma-gamma coincidences were measured. Multipolarities of the transitions were extracted assuming stretched transitions. The positive and negative parity bands have been extended up to spins 39/2+ and 43/2-, respectively. The proposed level scheme above J = 25/2 cannot be well understood on the basis of the spherical shell model calculations with valence protons occupying the (1f5/2,2P3/2,2P1/2,1g9/2) configuration space. The breaking of the N = 50 neutron core appears to be a plausible mechanism for the observed high spin states.
