The Low Lying Excited Electronic States of an Alkali Earth Compounds

Since there is lack in the excited electronic states of alkaline earth compound, candidate for ultracold investigation, and by using an ab initio calculation the potential energy curves have been obtained for the lowest electronic states in the 2s+1Λ(±) representation below 53000 cm-1 along with the harmonic frequency we, the internuclear distance re, the rotational constant Be, and the electronic energy with respect to the ground state Te. The comparison of these values to the theoretical and experimental results available in the literature shows a good agreement. (author)
