EN

Quantum close-coupled calculations of the collisional self-broadening of the 540.06 nm neon line (3s[3/2]_{1}-3p'[1/2]_{0}) are presented for temperatures from 70 K to 900 K. These calculations are based on the quantum-mechanical impact theory of Baranger and represent the interatomic interaction by adiabatic molecular potentials calculated using model potentials for the electron- atom and atomic core-core interactions. The calculated widths and shifts vary smoothly with temperature and are accurately given across the temperature range by fourth order polynomial fits.
