摘要：
We solve the Schrodinger equation with the improved expression of the Manning-Rosen empirical potential energy model. The rotation-vibrational energy spectra and the unnormalized radial wave functions have been obtained. The interaction potential energy curve for the a(3)Sigma(+)(u) state of Li-7(2) molecule is modeled by employing Manning-Rosen potential model. Favorable agreement for the Manning-Rosen potential is found in comparing with ab initio data. The vibrational energy levels predicted by using the Manning-Rosen potential for the a(3)Sigma(+)(u) state of Li-7(2) are in good agreement with the RKR data and ab initio determinations.
