The directional correlation between the first forbidden non-unique 2.31 Mev beta transition and the successive 0.603 Mev gamma ray in the decay of Sb/ sup 124/ were measured at eight beta -ray energies. A thin lens spectrometer with a momentum resolution of 7% was used for the analysis of the beta -ray energy. The measured angular correlation coefficient epsilon ranges from --0.28 plus or minus 0.03 to --0.404 plus or minus 0.008 in the energy interval 1.24 to 2.09 Mev. An analysis of the data in the ''modified B, approximation'' is consistent with the experiment and yields two possible values for the matrix element ratio Y. From this, the magnitude of the nuclear matrix elements contributing to the decay can be extracted. (auth)
