摘要：

The high-spin structure of Tc-91 has been studied by means of gamma-spectroscopy. Tc-91 was produced by use of the Ni-58(Ca-40,alpha3p)Tc-91 reaction at beam energies of 180 and 187 MeV. The NORDBALL detector system including charged particle and neutron selection was used. A large number of positive as well as negative parity states with excitation energies up to 12 MeV and spin values up to (47/2, 49/2) has been established. The level scheme has been compared with shell model calculations using both Sr-88 and 100Sn as cores. Some first information of the level scheme of Tc-90 is also given.
