Abstract

We report here (Lambda) -doubling splitting and permanent electric dipole moment d_p measurements for a number of vibrotational levels of NaK D ¹II state. Two different methods, which are not Doppler limited, were used. Stark effect induced level crossing was registered as fluorescence polarization changes with external electric field, which allowed us to obtain, from one fit, the values of electric dipole moment and (Lambda) -doubling splitting (Delta) _ef between e, f substates of an individual rotational state. Another method consisted in obtaining the ratio (Delta) _ef/d_p from electric field dependence of the intensity of forbidden line appeared in fluorescence as a result of e- f Stark mixing, along with direct (Delta) _ef measurements by optical-rf double resonance. Signal simulations and data fitting were accomplished using direct Hamiltonian diagonalization accounting for Stark interaction within rotational states J plus or minus (Delta) J, (Delta) J equals 0, 1, 2 in initial, excited and final state. Dipole moment values obtained confirm theoretical predictions.
