| Sumario: | The nonrelativistic impulse approximation for the induced-tensor interaction has been analyzed in detail. ft values for mirror transitions have been calculated using electron Coulomb wave functions for the extended charge distribution and introducing higher-order corrections. 14 angular β-γ correlations, the β transition being allowed, have been analyzed, showing that this process is sensitive to the presence of the induced-tensor interaction. The amount of information about the induced tensor at present obtainable from circular γ polarization in nuclear transitions has been investigated. A limit on the induced-tensor coupling constant has been obtained which does not contradict the evidence based on ft values. β-γ angular correlations seem to yield evidence for the weak-magnetism term, while not excluding the existence of the induced tensor. © 1972 The American Physical Society.
