  :I don't think so.  Consider the processes internal conversion and electron capture.  They occur when an electron (usually a K-shell electron) is actually inside the nucleus.  The nucleus can't interact with part of an electron.  The probability of interaction varies with the probability of the electron being inside the nucleus - heat up Be-7 (which decays by K-capture) a few thousand degrees and the half-life increases, because you've ionized away the electrons from the K-shell.
