Special attention devotes to the correspondence between dissipative and diffusive terms of these equations. For the case when the particle moment of inertia is negligible small, the effective system of Langevin equation for spherical coordinates is obtained. This system contains two equations with additive noises and can be readily treated numerically. We confirm our analytical finding by numerical simulation. popup.nrat_date 2025-05-12 Close
