Abstract
We discuss the A-B transition of superfluid He-3 in a slab with rough surfa ces using the quasi-classical theory in the weak coupling approximation. Th e superfluid transition temperature is presented as a function of the slab width for various roughness parameters. The surface roughness suppresses th e A phase order parameter parallel to the surfaces, and thus favors the B p hase. This agrees with the results of a Ginzburg-Landau theory by Li and Ho .
