We investigate the attractive interaction between spatial solitons in nematic liquid crystals with a tunable nonlinearity and a constant nonlocality.The experimental study, carried out by controlling the orientation of the optic axis via the electro-optic response,shows how the interactions depend on reorientation, in excellent agreement with a model accounting for the anisotropic nature of the dielectric.
