Research On Franck-Condon Factors And Transition Frequency Of Alkaline-earth Hydrides, Alkaline-earth Fluorides And Alkaline-earth Oxides

In this report we investigate the potential energy curves and related Franck-Conden factors (FCs) of the A2Π-X2Σ+ system of the alkaline-earth hydrides, alkaline-earth oxides and alkaline-earth fluorides. Take MgH as an example, its Frank-Condon factors and related transition band origins of the A2Π-X2Σ+ system were obtained experimentally and theoretically. In following, we will describe our works in details.Firstly, we experimentally measure the dispersed fluorescence of the R(1/2) line of the (0,0) band of the A2Π-X2Σ+ system of the MgH using Laser Ablation/Laser Induced Fluorescence method. And we obtain the Franck-Conden factors and band origins of the A2Π(V’=0)-X2Σ+ (v"=0,1) by analyzing our data.Secondly, we use RKR inversion method to get the potential energy functions of A2Π and X2Σ+ of MgH. And we numerically solve the radial Schrodinger equation and get the eigen energies and eigen wave functions of their vibration levels. So we can get the Frank-Condon factors and the transition frequencies.By comparison, we found the Frank-Condon factors and related transition frequencies of A2Π-X2Σ+ from experimentally are consistent with the result from theoretically. And then, we used these results compare with the result from other authors. And the result is very significant to the experiment of laser cooling.
