J^{π}(level): From 1991Va04 (assignments based on degree of hindrance of α groups to levels with known structure in ^{188}Tl and on systematics of neighboring odd-odd Bi isotopes).

Identification: mass separation of products from

^{181}Ta(^{20}Ne,xn) (1970Ta14); excitation functions for^{203}Tl(^{3}He,xn) and^{159}Tb(^{40}Ar,xn) (1974Le02).The activity (T

_{1/2}=74 s5, Eα=5892 keV5), assigned to^{192}Bi or^{196}Bi by 1967Tr06, was reassigned to^{193}Bi by 1970Ta14; the activity (T_{1/2}=38 s5, Eα=6050 keV5), assigned to^{191}Bi or^{195}Bi by 1967Tr06, probably arises from^{192}Bi.Theory:

Calculations using Coulomb and proximity potential model: T

_{1/2}, and HF for α decay from g.s. and (10-) isomer (2011Sa10).Q-value: Note: Current evaluation has used the following Q record

Q-value: Values are from 2011AuZZ (cf. 5470

40, 838030, 59050and 63765, respectively, from 2003Au03).Q-value: Q(α): both

^{192}Bi (3^{+}) and^{188}Tl (2-) assumed to be ground states for relevant nuclides.
