Description

A nonperturbative approach to the description of spectral line shapes of Ly-α radiation produced by multicharge ion-pair collisions is proposed. A closed expression that describes the central part of the line as well as the wings with an oscillation structure due to the extremum in the difference between the potential-energy curves has been obtained. It has been found that the exchange interaction leads to the formation of two satellites in the red and blue wings of the Ly-α perpendicular transitions
