【Abstract】 An experimental study of the process Rb(5 2 P 3/ 2 )+Rb(5S)+nhν→Rb(7 2 D J )+Rb(5S)+ (n-1)hν is reported, where nhν represents a radiation field of n photons hav ing frequency ν. The frequency ν is tuned in the wings of the Rb7D 3/2 →5P 3/2 transition. The branching ratio of I(7D 3/ 2 →5P 1/2 /I(7D 5/2 →5P 1/2 ) has been measured. The measurements show the interatomic potentials and nonadiabatic effects take important roles in the dissociation dynamics.更多还原
