We present a study of the role of fermions in the decay of metastable states of a scalar field via bubble nucleation. We analyze both one- and three-dimensional systems by using a gradient expansion for the calculation of the fermionic determinant. The results of the one-dimensional case are compared to the exact results of previous work. {copyright} {ital 1997} {ital The American Physical Society}
