The Deng–Fan potential is used to discuss the reliability of the improved Greene–Aldrich approximation and the factorization recipe of Badawi et al [] for the central attractive/repulsive core J J + 1 / 2 &mgr; r 2 ?> . The factorization recipe is shown to be a more reliable approximation and is used to obtain the rotational–vibrational energies for the a 3 &Sgr; u + ?> –7Li2 dimer. For each vibrational state only a limited number of the rotational levels are found to be supported by the a 3…
