Abstract

Usually, it's difficult for us to observe the Compton Scattering in an atom. One way to overcome this difficult is using multi-photon collide with an atom, which will come into being multi-photon Compton Scattering (MCS) phenomenon. Thus, we can investigate the MCS process in visible light region. During the MCS process, the cluster atoms moving as a whole, namely atomic Dicke states, the multi-photon interacting with cluster atoms. We can observe a significant Doppler shift of resonant fluorescence spectrum(RFS)in a room-temperature two-levelatomic system. In this paper, we present a detail analysis of the physics mechanism of the Doppler shift and propose a method to measure the component of the Dicke states (the atomic polymers with different masses)by using the Doppler shift of the RFS.
