Query: New Families of Isospectral Hydrogen-like potentials   By applying algebraic techniques, we construct a two-parametric family of
strictly isospectral Hydrogen-like potentials as well as some of its
one-parametric limits. An additional one-parametric almost isospectral family
of Hydrogen-like potentials is also investigated. It is argued that the
construction of a SUSY partner Hamiltonian using a factorization energy
$\delta$ less than the ground state energy of the departure Hamiltonian is
unnecessarily restrictive.
