  We analyze d-wave resonances in atom-atom scattering in the presence of
harmonic confinement by employing a higher partial wave pseudopotential.
Analytical results for the scattering amplitude and transmission are obtained
and compared to corresponding numerical ones, which employ the Lennard-Jones
potential. Qualitative agreement is observed for weak confinement. For strong
confinement the pseudopotential does not capture the s- and d-wave interference
phenomena yielding an asymmetric Fano profile for the transmission resonance.
