Abstract
A simple model for the description of atomic and ionic species with sp ectra exhibiting a quantum defect is solved using the Lie algebra su(1 , 1). The quantum defect of bound states is related to the phase shift of scattering states. The resonances are discussed in terms of the no nunitary representations of this algebra.
