摘要：

In order to calculate the opacity of a gas it is necessary to consider how its constituent atoms are perturbed by the surrounding medium. This is required both in order to calculate the equation of state, and in order to determine the profiles of the spectrum lines. In this work we report new theoretical Li line profiles perturbed by H-2 and their dependence with temperature. (C) 2013 COSPAR. Published by Elsevier Ltd. All rights reserved.
