Abstract
The effects of solitons on the spectrum of fermion excitations in superfluid - are investigated. It is found that there is a two-dimensional manifold of bound states with energies within the gap of the bulk superfluid. The bound-state spectrum lacks inversion symmetry parallel to the wall.
