  The half-life of 46V has been measured to be 422.66(6) ms, which is a factor
of two more precise than the best previous measurement. Our result is also
consistent with the previous measurements, with no repeat of the disagreement
recently encountered with Q_{EC} values measured for the same transition. The
Ft value for the 46V superallowed transition, incorporating all world data, is
determined to be 3074.1(26) s, a result consistent with the average Ft value of
3072.08(79) s established from the 13 best-known superallowed transitions.
