High Resolution Laser Excitation Spectra and Franck-Condon Factors of A2Π-X2Σ+Electronic Transition of MgF
文献摘要：
Magnesium monofluoride(MgF)is proposed as an ideal candidate radical for direct laser cooling.Here,the rotationally resolved laser spectra of MgF for the A2Π-X2Σ+electronic transition system were recorded by using laser induced fluorescence technique.The MgF radicals were produced by dis-charging SF6/Ar gas mixtures between the tips of two magnesium needles in a supersonic jet expan-sion.We recorded a total of 19 vibrational bands belonging to three sequences of Δv=0,±1 in the region of 348-370 nm.Accurate spectroscopic con-stants for both X2Σ+and A2Π states are deter-mined from rotational analysis of the experimen-tal spectra.Spectroscopic parameters,including the Franck-Condon factors(FCFs),are determined from the experimental results and the Rydberg-Klein-Rees(RKR)calculations.Significant discrepancies between the experimentally measured and RKR-calculated FCFs are found,indicating that the FCFs are nearly independent of the spin-orbit coupling in the A2Π state.Potential energy curves(PECs)and FCFs determined here provide necessary data for the theoretical simulation of the laser-cooling scheme of MgF.
