Abstract

It is shown that the renormalization of the weak-axial charge density due to the mesonic exchange effects leads to a reduction of the one-body shell-model log z.hfl;t values for the β-decays 206Hg(0+) → 206Tl(0), and 206Tl(0) → 206Pb(0+) by about two units and gives a satisfactory agreement with experiment.
