SELF-BROADENING OF 2P(5)3P-2P(5)NS (N=5, 6) NEON LINES

Quantum close-coupled calculations of the collisional self-broadening of neon lines involving transitions whose upper level is either 5s'[1/ 2](1.0), 5s'[3/2](1.2), 6s'[1/2](1.0) or 6s[3/2](1.2) and lower level is 3p[1/2](1), 3p[3/2](1.2), 3p'[3/2](1.2) or 3p[5/2](2) are presented for temperatures between 70 and 400 K. These calculations are based o n the quantum-mechanical impact theory of Baranger in which the intera tomic interaction is represented by adiabatic molecular potentials cal culated using model potentials for the electron-atom and atomic core-c ore interactions. We discuss the complications arising from the contri butions of the highly excited 2p(5)ns (n = 5, 6) states and give param etric fits to the width and shifts of all lines in the temperature ran ge 70-400 K.
