INTERNAL CONVERSION COEFFICIENTS OF M1 GAMMA RAYS OF Au$sup 199$ AND Au$sup 19$$sup 5$
ABS>An attempt has been made to measure the internal conversion coefficients of the M1 + E2 radiations of Au/sup 199/ and Au/sup 195/ with sufficient accuracy to check the effect of the finite nuclear size on internal conversion in this region of Z. In the case of Au/sup 199/a a direct comparison of the 158-kev pure E2 transition with the 208-kev M1 + E2 radiation was possible. Comparison of the gamma-ray intensities determined from scintillation spectrometry with conversion line intensities measured in a small shaped-field spectrometer yielded K, L, M, total shell coefficients. Comparison of these gamma-ray intensities with conversion line intensities photographically recorded in a higher resolution permanent-field spectrometer led to L-subshell coefficients. The results for the 208-kev transition are: a/sub K/= 0.71 plus or minus 0.05, a/sub L/ - 0.144 plus or minus 0.01, a/sub LI/ = 0.114 plus or minus 0.007, a/sub LII/ = 0.0227 plus or minus (((((((((Unscannable abstract)))))))))))
