  Recently, for spinless non-relativistic particles, Norsen, Marian and Oriols
show that in the de Broglie-Bohm interpretation it is possible to replace the
wave function in the configuration space by single-particle wave functions in
physical space. In this paper, we show that this replacment of the wave
function in the configuration space by single-particle functions in the
3D-space is also possible for particles with spin, in particular for the
particles of the EPR-B experiment, the Bohm version of the
Einstein-Podolsky-Rosen experiment.
