Der Zerfall von Nb94 m
Using scintillation spectrometers and coincidence techniques the decay of Nb94 m has been investigated. TheK-shell conversion coefficient of the 41.5 keV isomeric transition was found to be 570±100 indicating aM 3 transition. The maximum energy of theβ-decay to the 0.87 MeV level of Mo94 is (1.15±0.03) MeV occurring (4·5±0·7)×10−3 per disintegration, anotherβ-decay to the 1.57 MeV level was found to be (4·0±1·3)×10−5. From this the parities and spins of the levels involved in the decay of Nb94 m are determined.
