We develop a new approach to build the eigenfunctions of a translationallyshape-invariant potential. For this we show that their logarithmic derivativescan be expressed as terminating continued fractions in an appropriate variable.We give explicit formulas for all the eigenstates, their specific formdepending on the Barclay-Maxwell class to which the considered potentialbelongs.

Rational solutions for the Riccati-Schr\"odinger equations associated to translationally shape invariant potentials
