ABSTRACT: High-spin states of 77Kr are studied via the fusion-evaporation reaction 68Zn(16O, 2p5n)77Kr with the beam energy of 80 MeV provided by the Tandem accelerator at Japan Atomic Energy Agency (JAEA). The intensity of the beam is I ? 1 pnA. In the present work, some new ? transitions are found to constitute the new band of the proposed level scheme. It is very similar to the M1 transition from the level energy, so it is proposed that this band is the M1 band.
