Q-Value for the Fermi Beta-Decay of 46V
Abstract
By comparing the Q-values for the 46Ti(3He,t)46V and 47Ti(3He,t)47V reactions to the isobaric analog 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.
