Abstract
For arbitrary values of n and l quantum numbers we present a simple exact analytical solution of the Ddimensional D ≥ 2 hyperradial Schrödinger equation with the Kratzer and the modified Kratzer potentials within the framework of the exact quantization rule EQR method The exact bound state energy eigenvalues E nl are easily calculated from this EQR method The corresponding normalized hyperradial wave functions ψ nl r are also calculated The exact energy eigenvalues for these Kratzertype potentials are calculated numerically for a few typical LiH CH HCl CO NO O2 N2 and I2 diatomic molecules for various values of n and l quantum numbers Numerical tests using the energy calculations for the inter dimensional degeneracy D = 2 − 4 for I2 LiH HCl O2 NO and CO are also given Our results obtained by EQR are in exact agreement with those obtained by other methods
