Abstract
Using the supersymmetric quantum mechanics, we investigate the wave
function-sensitive properties of the supersymmetric potentials which have
received a lot of attention in the literature recently. We show that a
superdeep potential and its phase-equivalent shallow-partner potential give
very similar rms radius values for the weakly bound systems such as the
deuteron and
nuclei. Although the corresponding eigenstates differ
in the node-number, our investigation on the
single
nucleon halo transfer reaction at 35 MeV show that also other physical
quantities such as the cross-section angular distributions calculated using
these wave functions reflect the nodal structure rather weakly. This lends
support to two nearly equivalent treatments of the Pauli principle.
