β−γCorrelations in the First Forbidden Transition

Abstract

A discussion is given of the theory of $\beta -\gamma$ correlations in the unique and nonunique first forbidden transition. In particular, numerical results are presented for the Coulomb corrections to the $\beta -\gamma$ directional correlation and transverse $\beta$ polarization—$\gamma$ correlation. The energy dependence of the contribution associated with violation of time-reversal invariance is given.
