The K{sub {alpha}}=x-ray yields associated with the superdeformed and normal-deformed bands in {sup 193}Hg have been measured. The results indicate an excess yield of K{sub {alpha}}-x rays in coincidence with the superdeformed cascade relative to that in coincidence with the normal-deformed cascade. The internal conversion of known transitions along the superdeformed cascade cannot account for the observed K{sub {alpha}}-x ray yield. It is likely that this excess x-ray yield is associated with low energy M1 transitions competing with the low-spin superdeformed E2 transitions. These M1 {gamma} rays are expected to connect the two superdeformed bands which are observed in coincidence with each other. Calculations based on the measured {gamma}-ray intensities indicate that within the experimental uncertainties the excess K{sub {alpha}} yield can be entirely accounted for by interband-M1 transitions. X-ray yields from the recent {sup 193}Hg EUROGAM experiment will also be discussed.
