We investigate theoretically and experimentally the three dimensional propagation and interaction of mutually incoherent screening spatial solitons in an SBN crystal. We show that the interaction of solitons results in complex trajectories which typically show partial mutual spiraling, followed by damped oscillations and the fusion of solitons. This nontrivial behavior is caused by the anisotropy of the nonlinear refractive index change in the crystal. © 1999 The American Physical Society.
