Abstract

A simple model based on 100% quenching of metastables by threshold electrons transmitted to short distances on the polarization potential is employed. Values of the quenching rate coefficients of 1.6 × 10-6 cm3 s-1 at threshold and 0.92 × 10-6 cm3 s-1 at 50 K are estimated for electron collisions with metastable xenon and 1.33 × 10-6 cm3 s-1 at threshold for metastable calcium.
