One conceivable basis for interlevel transfer from a long-lived isomer to a graser state might be to alter the multipolarity of the transfer step. As an example, in the case of /sup 119/Sn any mechanism that introduces angular momentum to admix M3 radiation into the normally M4 transition from the 89.6 keV, 11/2/sup -/ level to the 23.9 keV, 3/2/sup +/ state could greatly shorten its normal 293 day half-life. We have calculated the K-shell internal conversion rate for the 89.6 keV level in /sup 119/Sn for small admixtures of M3 radiation using Moszkowski formulas for the radiative transition rates and tabulated values of the internal conversion coefficients. We find that even very small admistures of lower multipole order can produce very large changes in the internal conversion coefficient. This offers the basis for a simple and definitive test of the hypothesized mechanism for creating population inversion by introducing angular momentum. 4 refs., 1 fig.
