Matrix Elements of the Linearized Collision Operator for Multi-temperature Gas-mixtures

For a mult i component and multi-temperature gas-mixture the matrix elements o f the linearized Bol tzmann collision operator are investigated for isotropic interaction potentials. The representation b y means o f Burnett basis functions simplifies the algebraic structure and enables closed expressions for the general results, which can also be used for an investigation o f inelastic collisions. For the elastic case those collision terms are given explicitely which appear in the balance equations for mass, momentum, energy and heat f lux-vector.
