摘要：
The beta+/EC decay of mass-separated (197m,g)Bi has been studied with the LISOL on-line separator. A decay scheme has been constructed on the basis of X, gamma and electron singles spectra and gamma-et, gamma-Xt and gamma-gamma-t coincidence data. Three types of levels are observed: the p3/2, f5/2, i13/2 and f7/2 neutron quasiparticle states, the coupling of the p3/2, f5/2 and i13/2 quasiparticles to the 2(1)+ level of the even Pb core and the coupling of the i13/2 quasiparticle to the 0(2)+ and 2(2)+ levels of the shell-model intruder states in the even-Pb core.
