We have performed a new exact evaluation of the fluctuation determinant κ of the electroweak sphaleron with Θ W = 0. The results differ significantly from a previous calculation of this quantity by Carson et al. We find that κ is of order 1 in units (gυ) 6 while the previous results indicated a strong suppression of the sphaleron transition by this factor.
