Abstract [en]

The integral equations of Gelfand and Levitan were previously used by Abraham and Moses (Phys. Rev. A, 22 (1980) 1333) to construct a modified local potential Vpert(r), which in this work is added to a coulombic potential in order to remove the lowest s state from the spectrum. The total modified potential Vnew(r), for excited states is used in conjunction with the shifted 1/D expansions of dimensional scaling. It is verified that it is feasible to find the lowest energies and the mean radius for Vnew, treating it now as a ground state problem. This indicates that a potential for excited states can be generated by the procedure, with the possibility of using it in the study of excited states and valence states. The potentials applied can be considered as local pseudopotentials.
