Electron excitation coefficients for 2p state of neon

Abstract

Electron excitation rate coefficients for the 2p state of neon atom, (from 2p 1–2p 10 in Paschen notation) have been measured using an electron drift-tube technique. The absolute excitation coefficients were obtained from the optical signal at the anode in Townsend neon discharges, after correction for the detector quantum efficiency. The data were obtained for the electric field to neon number density ratio ( E N ) from 20 Td to 4 kTd (1 Td = 10 −21 Vm 2). The absolute excitation coefficients for the 2p 1 level agree with the results of Tachibana [1], which are the only experimental data available in the literature.
