BETA-GAMMA CORRELATIONS FROM POLARIZED MANGANESE-52

A recent calculation by Curtis and Lewis and by Morita and Morita gives a distinction and correlation function for the beta and subsequent gamma radiations from oriented nuclei in a j-j beta transition. An experimental determination of the parametric in this function can give information on the magnitude and relative phase of the fermi and Gamow-Teller interactions involved. Such experimental determinations on polarized Mn/sup 52/ have been made. In order to evaluate each parameter uniquely, certain assumptions must be made about the nature of the beta interactions. The recent experiments on Ar/sup 35 and Ne/ sup 19/ and the balanced recoil experiment on Eu/sup 152/ using resonance fluorescence techniques, together with the reevaluation of the He/sup 6/ recoil experiment, indicate that vector and axial vector are the predominant forms of the Fermi and Gamow-Teller interactions, respectively. Furthermore nearly all of the recent experiments measuring the longitudinal polarization of electrons and positrons and also their angular distribution in beta decay are in accord with the two-component neutrino hypothesis where neutrinos of negative helicity are emitted in both Fermi and GamowTeller decays.
