Abstract

The excited states in 107Ag were populated through the heavy-ion fusion evaporation reaction 100Mo (11B, 4n) 107Ag at a beam energy of 46 MeV. Lifetimes of high-spin states in 107Ag have been measured through the Doppler shift attenuation method. The deduced B(M1) values, gradually decreasing with increasing spin, clearly demonstrate that both the yrast positive-parity band and the yrast negative-parity band in 107Ag are magnetic rotation bands. Furthermore, experimental deduced B(M1) values for the yrast positive-parity band are compared with the predictions of the particle rotor model. The approximate agreement between theoretical calculations and experimental results further confirms the mechanism of magnetic rotation for the yrast positive-parity band. In addition, a systematic investigation shows the evolution of the magnetic rotation mechanism in the A≈110 mass region.
