摘　　要：We study the correlation statistics of phonon radiations in a weakly driven optomechanical system.Three dominated scattering processes are identified by the scattering theory analytically and the master equation numerically,whose interplay determines the phonon statistical properties.Our results show that for the large detuning,the driving field off-resonant with the system induces a small emission rate of two anti-bunched phonons.For the resonant driving field,there is a relatively large emission rate of two bunched phonons.
