Abstract

Quasiclassical methods are used to study the reflection of wave packets at diffusely scattering surfaces of ${}^{3}{He}$ . In addition to conversion into nonmagnetic and magnetic holes and partial specular reflection into nonmagnetic and magnetic wave packets, diffuse background scattering of nonmagnetic and magnetic particles and holes into all directions is found. The calculations are based on the self-consistently computed order parameter in the vicinity of the wall.
