Abstract
We compute the generating function for the moments of the creation and annihilation operators of a single mode radiation field described by a Gaussian Wigner distribution. It is shown that the moments of this field can be calculated by making use of Hermitian polynomials of two variables. Moreover, the moments of a generalized radiation field introduced recently by G.S. Agarwal [Phys. Rev. A 45 (1992) 1787] are computed as well.
