Abstract
We have studied the ionic charge state dependence of the nuclear lifet ime of the 35.5-keV first excited state of Te-125. We found for the 47 (+) and 48(+) ions, 400 and 670 % variations with respect to the neutr al-atom half-life (1.49 ns). These unusually large effects are due to the energetic blocking of the K-shell internal conversion as the charg e state increases past 47(+). For the 46(+), we suggest a new internal conversion mode without any electron emission into the energy continu um.
