| 0.0 | (3/2-) | 210 ms +60-40 % α ≈ 100 | Eα=7340 keV 20 (1996Le09) correlated with Eα=6728 keV 15 (201Rn); Eα=7350 keV 25 (1995Le15); Eα=7360 keV 20 (1987He10), but the energy resolution of the experimental system was not sufficient to resolve it from Eα depopulating the Jπ=(13/2+) isomer. E(level): Eα=7340 keV 20 (1996Le09) correlated with Eα=6728 keV 15 (201Rn); Eα=7350 keV 25 (1995Le15); Eα=7360 keV 20 (1987He10), but the energy resolution of the experimental system was not sufficient to resolve it from Eα depopulating the Jπ=(13/2+) isomer. |
