Abstract :
The problem of nonlinear isotropic homogeneous gas relaxation is solved for pseudo-power cross section in the velocity range of up to 10 thermal velocities at various initial conditions. A new analytical expression for isotropic collision integral kernel and a new algorithm of collision integral estimation are used in the calculations.
