We discuss the phase-space representation of the Bloch equation and present analytic expressions for two generalized classes of distribution functions. Series solutions to order of Latin small letter h with stroke2 are given. We conclude that the Wigner quantum corrections are the simplest among the two general classes of distribution functions. © 1985 The American Physical Society.
