Let + be a nondegenerate Gaussian measure on a Hilbert space H. For an arbitrary selfadjoint nonnegative operator A we consider the semigroup e tL = 1(e &tA ) on L p (+), where 1 stands for the second quantization operator. We provide an explicit characterization of the domains of (I&L) mÂ2 in L p (
