We have measured the first [1] and second order correlation functions of the light spontaneously emitted from a two ion crystal. The experimental measured g(2)(t=0) shows bunched or antibunched light, depending on the angle of photon observation and the distance between both ions. The data are compared to a theoretical expectation for the correlation functions using a master-equation approach. In this calculations we take ion motion, the excitation laser power and direction of the driving laser beam into account as well as the observation angle. Future experiments with two detectors at different positions are discussed where again a spatial modulation is predicted [2]. We investigate the feasibility of such experiments under realistic experimental conditions.
