Abstract: | In a pair of atoms in collision, the polarizability of the system depends on the relative velocity. The mechanism introduced here implies the time dependence of the effective field acting on the partners. The linear term of the expansion with respect to the velocity suggests the existence of an optical activity for a monatomic fluid submitted to a non-uniform flow. |
