Abstract Using the perturbed γ-γ angular correlation at excited111Cd-ions from the decay of111In, the time-integral attenuation coefficientG 22(∞) was measured in gaseous InCl and InCl3 surroundings. The perturbation depends as well on the character and the density of the surrounding gas, as on the angular momentum of the electronic shell of the Cd-ion.G 22(∞) varied between 0.012 and 0.828, while the molecule densities varied between 2×1014 and 2×1020 molecules/cm3. For high densities it is to be noted, that the perturbation vanishes much faster for the InCl systems. Using a stochastic model, it is possible to calculate the mean hyperfine frequency Ω0, and to estimate cross-sections for molecule-ion collisions at thermal energies.
