ABS>The effect of the pion cloud to the ratio g/sub A//g/sub V/ in the ore resistant t decay is investigated with the assumption of the conserved current for the vector interaction. The three-pion state is considered as the simplest state which might improve the result of the static theory, which gives g/ sub A//g/sub V/ < 1. According to the lowest order perturbation calculation, the contribution from this state turns out to be of the positive sign and large. It seems promising to explain the observed ratio g/sub A/, g/sub V/> 1 ewn-en when the decrease of the bare state probability is taken into account, unless the effect of the suppression of the nucleon pair is tco strong.
