Theoretical study of pressure broadening of lithium resonance lines by helium atoms

Zhu, Cheng; Babb, James F.; Dalgarno, Alex (American Physical Society, 2005)

Quantum mechanical calculations are performed of the emission and absorption profiles of the lithium 2s-2p resonance line under the influence of a helium perturbing gas. We use carefully constructed potential energy surfaces ...
Theoretical study of sodium and potassium resonance lines pressure broadened by helium atoms

Zhu, Cheng; Babb, James F.; Dalgarno, Alex (American Physical Society, 2006)

We perform fully quantum mechanical calculations in the binary approximation of the emission and absorption profiles of the sodium 3s-3p and potassium 4s-4p resonance lines under the influence of a helium perturbing gas. ...
