Death and revival phenomena can be observed in many areas in quantum physics and can appear in different aspects and forms. We investigate the time behavior of spontaneous emission of a three-atom system which collectively shares a single excitation. Two atoms are assumed to be closer than a wavelength to each other, while the third atom is many wavelength away. In a detailed analysis we demonstrate that at certain detector positions the spontaneous emission of the photon can display a birth, i.e., the probability to detect the photon does not decay as a function of time but increases from zero, or a non-periodic death, i.e., the photon detection probability drops to zero, followed by a revival of the signal. We further show that the spontaneous emission process of the fully excited system can be monitored by higher order intensity correlation measurements.
