  The strictly isospectral double Darboux method is applied to the quantum Taub
model in order to generate a one-parameter family of strictly isospectral
potentials for this case. The family we build is based on a scattering
Wheeler-DeWitt solution first discussed by Ryan and collaborators that we
slightly modified according to a suggestion due to Dunster. The strictly
isospectral Taub potentials possess different (attenuated) scattering states
with respect to the original Taub potential
