摘要
The high-spin states in the odd-odd nucleus As-74 were studied via heavy ion fusion evaporation reaction Zn-70(Li-7, 3n)As-74 at a bombarding energy of 30 MeV. A level scheme with 43 new gamma transitions and 28 new levels has been established. Signature inversion has been observed in the yrast bands. And the mechanism of signature inversion has been explained within the framework of two quasiparticles plus rotor model.
