Abstract Absolutely calibrated emission spectroscopy has been used to determine the particle number densities of XeCl*(B), XeCl*(C), and Xe2Cl* in a small scale Ne/Xe/HCl discharge with well-defined current and voltage pulses for a wide range of parameters. The measured particle number densities could be reproduced quite well by numerical model calculations using the rate-coefficient values of Quiñones et al. [1] for the quenching of XeCl*(B,C) by Ne, Xe, and 2Xe, but 3.0 × 10−31 cm6/s for the formation of Xe2Cl* by (Ne + Xe)-quenching. For the electron quenching, we recommend a rate coefficient value of 3.2 × 10−8 cm3/s. From the equilibrium ratio of the particle number densities of XeCl*(C) and XeCl*(B), the energy separation between these states has been estimated to be 72 ± 33 cm−1 with the B state placed above the C state.
