Quantum mechanical potentials satisfying the property of shape invaria
nce are well known to be algebraically solvable. Using a scaling ansat
z for the change of parameters, we obtain a large class of new shape-i
nvariant potentials which are reflectionless and possess an infinite n
umber of bound states. They can be viewed as q-deformations of the sin
gle soliton solution corresponding to the Rosen-Morse potential. Expli
cit expressions for energy eigenvalues, eigenfunctions and transmissio
n coefficicnts are given. Included in our potentials as a special case
is the self-similar potential recently discussed by Shabat and Spirid
onov.
