Abstract
It is shown that the relation between kernels L l (v, v 1) of the linear collision integral and kernels G l l,0 (v, v 1, v 2) of the nonlinear collision integral can be reduced to the Laplace transformation. Analytic expressions for nonlinear kernels G +00,0 (v, v 1, v 2) and G +11,0 (v, v 1, v 2) are determined for hard spheres and pseudo-Maxwellian molecules.
