Abstract The stationary atomic population, the angular distribution and total radiation intensity of the scattered radiation for a system of two atoms interacting with a broadband squeezed vacuum are calculated including an arbitrary separation between the atoms. It is shown that in the squeezed vacuum the collective atomic states are populated with different probabilities. For a small interatomic separation the population of the subradiant state is greater than the population of the superradiant state. As the interatomic separation increases, the atomic population oscillates between these two states. We find that this difference in the populations leads to a nonspherical symmetry of the scattered radiation and a strong dependence of the total radiation intensity on the interatomic separation. These features are completely absent when the atoms interact with the thermal (black-body) field at a temperature T.
