We investigate theoretically properties of partially coherent solitons in optical nonlinear media with slow
saturable nonlinearity. We have found numerically that such a medium can support spatial solitons which are
asymmetric in shape and are composed of only a finite number of modes associated with the self-induced
waveguide. It is shown that these asymmetric spatial solitons can propagate many diffraction lengths without
changes, but that collisions change their shape and may split them apart. S1063-651X 99 12808-3
