High spin states in the [ital N]=50 nucleus [sup 93]Tc were populated and studied using the reaction [sup 66]Zn ([sup 31]P, 2[ital p]2[ital n])[sup 93]Tc 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[sup +] and 43/2[sup [minus]], respectively. The proposed level scheme above [ital J]=25/2 cannot be well understood on the basis of the spherical shell model calculations with valence protons occupying the (1[ital f][sub 5/2],2[ital p][sub 3/2],2[ital p][sub 1/2],1[ital g][sub 9/2]) configuration space. The breaking of the [ital N]=50 neutron core appears to be a plausible mechanism for the observed high spin states.
