Abstract:
Summary We have studied the absorption of light induced by a resonant or near-resonant collision between two atoms. The calculations have been performed by taking into account also the magnetic sublevels, which makes our theoretical predictions more applicable to realistic cases. Analytical expressions for the far-wing absorption cross-section have been obtained.
Keywords:Line shapes  widths  and shifts
