The use of solid rare gas matrices as detectors of metastable oxygen atoms is investigated. A 100 eV electron beam colliding with N2O target gas is used as the source of O(1S). The parameters considered are surface temperature, time delay of excimer emission and spectral response to O(1S). In all cases, detector sensitivity maximized at temperatures ≤20 K. Krypton was found to provide the most sensitive surface and neon the least.
