We consider two short-range repulsive interactions, viz. Hellmann potential form and a new potential form recently suggested by us. Our calculations are also made by taking into account the contributions of effective charge parameter in coulomb interaction. The results obtained from the new interaction potential is in better agreement with the experimental values than those obtained from Hellmann potential. The present investigation also provides a theoretical basis for the presence of ionic as well as polarised covalent bonding in diatomic heavy metal halide molecules.
