  abstract  = {If an atom is able to exhibit macroscopic dark periods, or electron shelving, then a driven system of tow atoms has three types of these fluorescence types as a simple and easily accessible indivator of cooperative effects. As an examble, we study two dipole-interacting V systems by simulation techniques. We show that the durations of the two types of light periods exhibit marked sepatation-dependent oscillations and that they vary in phase with the real part of the dipole-dipole coupling constant.},
