摘要

We study the structure and decay properties of triaxially deformed odd-A proton emitter (147,147)mTm with the modified particle-rotor model, which utilizes the microscopic nonadiabatic quasiparticle approach. In this approach the core spectrum is coupled with the particle states and hence the rotor properties are carried forward to the odd-A system. We demonstrate the merits of this approach by explaining the measured rotational bands in the triaxial proton emitters Ho-141 and (TM)-T-145,147. With our calculated spectra and half-lives for the proton emission, we confirm the ground state of Tm-147 to be 11/2(-) and predict the positive parity isomeric state to be 5/2(+).
