L-shell internal ionization has been observed in the $beta$ decay of $sup 203$Hg. A spectrum of Tl L x rays was obtained from a 0.12-$mu$C source of $sup 203$Hg in coincidence with 279-keV x rays from $sup 203$Tl. The coincidence requirement served to eliminate internal-conversion x rays from the spectrum. The total L-shell internal ionization probability P/subL/ obtained after normalization to the measured singles x-ray intensity was found to be (12.9+-0.5) x 10$sup -4$. Estimates for the individual L-subshell internal ionization probabilities resulted in values of (0.0+-6.5) x10$sup -4$, (4.8+-2.3) x10$sup - 4$, and (8.1+-3.5) x10$sup -4$ for P/sub L/sub I//, P/sub L/sub II//, and P/sub L/ sub III//, respectively. The measured value of P/subL/ is over 4 standard deviations higher, and that of P/sub L/sub III//, over one standard deviation higher, than theoretical predictions. (AIP)
