We have studied the atomic charge state dependence of the nuclear lifetime of the 35.5-keV first excited state of {sup 125}Te. For the 47{sup +} and 48{sup +} ions, 300% and 640% increases, respectively, of the half-life were found with respect to the neutral-atom value (1.49 ns). These unusually large effects are due to the energetic blocking of {ital K}-shell internal conversion as the charge state increases past 47{sup +}.
