Abstract

Quantum mechanical calculation of the total Penning ionization cross section for Ne(3P1) by O2 has been made. The interaction potentials of Ne(3P2,0) by O2 obtained from the literature are employed. The imaginary part of the optical potential at long range is expressed by a dipole–dipole autoionization width and at a small interatomic distance by an electron-exchange autoionization width. Γex is individually evaluated in the present work by fitting the calculated to σM at the mean collisional energy corresponding to room temperature. The calculation and comparison show that good agreement between the calculated results and experimental results has been obtained both in the absolute cross sections and in the energy dependence.
