The formation of free excitons in solid Xe from photogenerated electron–hole pairs was investigated with time‐resolved luminescence spectroscopy. The initial kinetic energy of the photocarriers was varied over a large range by an appropriate choice of photon energy of excitation. The decay curves of the free‐exciton luminescence yield a cascade‐type behaviour. The experimental results were reproduced with model calculations including thermalization via scattering on acoustic phonons and a recombination cross‐section which depends on the actual carrier temperatures. Good agreement between experiment and theory was found.
