We have applied partial algebraization technique to the cut-off Coulomb potential -Ze²/(r+b). It has been found that for a spin j representation 2j+1 exact solutions are obtained but they belong to excited states of potentials for different values of b. Degeneracies observed in the spectrum have been compared with exact numerical results.
