In superdeformed, heavy nuclei at low spins, {ital M}1 transitions enhanced by internal conversion are expected to compete favorably with {ital E}2 {gamma} rays. For strongly coupled bands with fairly large {ital B}({ital M}1) values, the decay may proceed between the two signature partner bands with very few {gamma} rays emitted. Measured {ital E}2 {gamma} ray intensities may imply strict limits on the {ital M}1 strength. Experimental evidence for the {ital M}1 cross talk dominated by internal conversion is seen in superdeformed bands in {sup 193}Hg.
