    "abstract": "We present a theoretical profile of the Lyman Beta line of atomic hydrogen\nperturbed by collisions with neutral hydrogen atoms and protons. We use a\ngeneral unified theory in which the electric dipole moment varies during a\ncollision. A collision-induced satellite appears on Lyman Beta, correlated to\nthe B\u0027\u0027\\barB 1Sigma+u - X 1Sigma+g asymptotically forbidden transition of H_2.\nAs a consequence, the appearance of the line wing between Lyman Alpha and Lyman\nBeta is shown to be sensitive to the relative abundance of hydrogen ions and\nneutral atoms, and thereby to provide a temperature diagnostic for stellar\natmospheres and laboratory plasmas.",
