| Abstract: | The Na K vapor is excited by the fixed frequency line 488.0 nm of the Ar laser. The NaK excited state is depopulated by radiative decay, predissociation and excitation transfer collision with the ground state atoms. By combining ratios of atomic to molecular fluorescence with the NaK( E ) state lifetime, all studied as a function of K density, the absolute rates for predissociation and collisional excitation transfer have been obtained. |
