摘      要：We report on experimental measurements of the transition dipole moments(TDMs)between the intermediate state 5s5p^(3)P_(1)and the triplet Rydberg series 5sns^(3)S_(1)in an ultracold strontium *** n is the principal quantum number ranging from 19 to *** transition 5s5p^(3)P_(1)–5sns^(3)S_(1)is coupled via an ultraviolet(UV)beam,inducing Autler–Townes splitting of both *** a splitting of the intermediate state is spectroscopically measured by using absorption imaging on a narrow transition 5s^(21)S_(0)–5s5p^(3)P_(1)in an ultracold gas of strontium *** power and size of the UV beam are carefully determined,with which the TDMs are extracted from the measured Autler–Townes *** experimentally obtained TDMs are compared to the calculations based on a parametric core potential,on a Coulomb potential with quantum defect,and on the open-source library Alkali Ryderg calculator,finding good agreement with the former two models and significant deviation with the latter.
