The author studies the coherence and excitation transfer in non-resonant second kind collisions between an optically excited mercury atom and a ground state cadmium atom : Hg(6 3P1) + Cd(5 1S 0) → Hg(6 1S0) + Cd(5 3P 1) + 1.08 eV. A model for the collision in which head-on collisions predominate is presented, and orientation and alignment transfer rates are calculated. In this model, the degree of orientation or alignment of cadmium atoms depends on the direction of the velocity of these atoms after the excitation process. The influence of nuclear spin is studied.L'auteur étudie le transfert d'excitation et de cohérence lors de collisions de seconde espèce non résonnantes entre un atome de mercure excité optiquement et un atome de cadmium d...
