Wepresent a zero-range pseudopotential applicable for all partial wave interactionsbetween neutral atoms. For p and d waves, we deriveeffective pseudopotentials, which are useful for problems involving anisotropic externalpotentials. Finally, we consider two nontrivial applications of the p-wavepseudopotential: we solve analytically the problem of two interacting spin-polarizedfermions confined in a harmonic trap, and we analyze thescattering of p-wave interacting particles in a quasi-two-dimensional system.
