ABSTRACT
By comparing the Q -values for the 46Ti ( 3He , t46V and 47Ti ( 3He , t47V reactions to the isobaric analogue states the Q -value for the superallowed Fermi decay of 46V has been determined as QEC( ^46V ) = (7052.11±0.27) keV. The result is compatible with the values from two recent direct mass measurements but is at variance with the previously most precise reaction Q -value. As additional input quantity we have determined the neutron separation energy Sn( ^47Ti ) = (8880.51±0.25) keV.
