Title: SHAPE OF BETA SPECTRA OF ONCE FORBIDDEN TRANSITIONS IN THE DECAYS OF Ga$sup 72$, La$sup 140$, Eu$sup 152$, Eu$sup 154$, AND Sb$sup 12$$sup 4$

Abstract

Magnetic spectrometer studies were made on the beta spectra of Ga/sup 72/ , La/sup 140/, E/sup 152/, Eu/sup 154/, and Sb/sup 124/. Th e highest energy beta group of each of these transitions has an abnormally long comparative half life and probably is a once forbidden decay from a 3-- initial state to a 2+ final state. The highest energy beta spectrum was found to have a nonstatistical, nonunique shape. On the assumption that the B/sub ij/ matrix element dominates the decay, the experimental shape factors were fitted empirically by C = q/sup 2/ + to 15, 10, 5, 20, and 15 for Ga/sup 72/, La/sup 140/ , Eu/sup 152/, Eu/sup 154/, and Sb/sup 124/, respectively.
