We have studied the ionic charge state dependence of the nuclear lifetime of the 35.5-keV first excited state of {sup 125}Te. We found for the 47{sup +} and 48{sup +} ions, 400 and 670{percent} variations with respect to the neutral-atom half-life (1.49 ns). These unusually large effects are due to the energetic blocking of the K-shell internal conversion as the charge state increases past 47{sup +}. For the 46{sup +}, we suggest a new internal conversion mode without any electron emission into the energy continuum. {copyright} {ital 1997} {ital The American Physical Society}
