Abstract
Quantum close-coupled calculations of the collisional self-broadening of neon lines involving transitions whose upper level is either , , or and lower level is , , or are presented for temperatures between 70 and 400 K. These calculations are based on the quantum-mechanical impact theory of Baranger in which the interatomic interaction is represented by adiabatic molecular potentials calculated using model potentials for the electron - atom and atomic core - core interactions. We discuss the complications arising from the contributions of the highly excited states and give parametric fits to the width and shifts of all lines in the temperature range 70 - 400 K.
