主　　题：photon recoil absorption spectroscopy ultracold strontium gas 

摘      要：We report on observing photon recoil effects in the absorption of a single monochromatic light at 689 nm through an ultracold ^(88)Sr gas,where the recoil frequency is comparable to natural linewidth of the narrow-line transition 5s^(2) ^(1)S_(0)-5s5p ^(3)P_(1) in *** the regime of high-saturation,the absorption profile becomes asymmetric due to the photon-recoil shift,which is of the same order as the natural *** lineshape is described by an extension of the optical Bloch equations including the momentum transfers to atoms during emission and absorption of *** work reveals the photon recoil effects in a simplest single-beam absorption setting,which is of significant relevance to other applications such as saturation spectroscopy,Ramsey interferometry,and absorption imaging.
