This note describes preliminary measurements of K-conversion electron-gamma correlation measurements in the two-step isomers, Te/sup 121/ and Te/sup 123/. In order to separate unambiguously the K and L correlations, a lens spectrometer has been employed for electron detection. To date, theoretical correlation coefficents are only available for the K shell. The isomers studied are of interest since conversion coefficient measurements indicate the second transition is predominately magnetic dipole, whereas shell model assignments would forbid ordinary M1 transitions. Partial breakdown of this selection rule would yield depressed M1 transition probabilities and might allow competition by the slower electric quadrupole transition.
