Findings

Calculated line profiles for multiple hydrogen series.

Quantified ion collision broadening effects.

Integrated ion and electron broadening mechanisms.

Abstract

We present theoretical calculations of the quasi-molecular line profiles for the Lyman (Lya, Lyb, Lyg, Lyd) and Balmer (Ha, Hb, Hg, Hd, He, H8, H9, and H10) series, perturbed by collisions with protons. In all calculations we include the dependence of the dipole moments as a function of internuclear distance during the collision. The broadening from ion collisions must be added to the normal electron Stark broadening.
