Additional Level Data and Comments:
E(level) | Jπ(level) | T1/2(level) | Comments |
0.0 | (0+) | 4.4 d 1 % ε = 100 | %α<0.01: not observed (no 4.4-d α activity and no 230Pa growth in 234Np was observed (1949Hy04)). E(level): %α<0.01: not observed (no 4.4-d α activity and no 230Pa growth in 234Np was observed (1949Hy04)). |
0.0+X | Possible configuration is Jπ=1-: π 5/2[523], ν 3/2[631]. E(level): Possible configuration is Jπ=1-: π 5/2[523], ν 3/2[631]. |
233U(p,3n) E=17-40 MeV. Measured cross sections (2005Aa02).
238U(p,5n), 232Th(7Li,5n) E=30-46 MeV. Measured fission excitation functions, fission fragment mass yields (1999Zh41).
