This paper generalizes some previous results presented in Gaioli et al. [Int. J. Theor. Phys. 36, 2167 (1997)]. We evaluate the autocorrelation function of the stochastic acceleration and study the asymptotic evolution of the mean occupation number of a harmonic oscillator playing the role of a Brow...
