THE EIGENVALUES OF THE SCHRODINGER-EQUATION FOR SPHERICALLY SYMMETRICAL STATES FOR VARIOUS TYPES OF POTENTIALS IN 2-DIMENSIONS, 3-DIMENSIONS AND N-DIMENSIONS, BY USING PERTURBATIVE AND NONPERTURBATIVE METHODS

The energy levels of the Schrodinger equation involving various model potentials in two, three and N-dimensional space, are calculated by using perturbative and non-perturbative methods. Our methods have been used effectively to calculate the energy eigenvalues even for high state numbers and large values of the perturbation parameters.
