On the ro–vibrational energies for the lithium dimer; maximum-possible rotational levels

Abstract

The Deng-Fan potential is used to discuss the reliability of the improved\nGreene-Aldrich approximation and the factorization recipe of Badawi et al.'s\n[17] for the central attractive/repulsive core. The factorization recipe is\nshown to be a more reliable approximation and is used to obtain the\nro-vibrational energies for the lithium dimer. For each vibrational state only\na limited number of the rotational levels are found to be supported by the\nlithium dimer.\n
