| 245+X | 0.75 ms 4 | 1991Va04 (from study of 194Bi α decay) suggest that the placement of 161.9γ from this isomer is incorrect for the following reasons: no (10-) to (8-) α transition observed, no coincidences observed between 5598α and 5660α with a possible (9-) to (8-) M1 γ transition, and E1 hindrance factor of 161.9γ is high by three to four orders of magnitude, as compared to those for neighboring Tl nuclides. | |
