%X Using fully incoherent white light emitted from an incandescent bulb （a line source） and amplitude mask, we study experimentally the interaction between two 21） white-light photovoltaic dark spatial solitons with three different separations （40μm, 50μm and 60μm） and arrangement directions （parallel to, perpendicular to and tilted at 45° with respect to the crystalline c axis） propagating in parallel in close proximity in seff-defocusing LiNbO3：Fe crystal. Experimental results reveal that a 21） white-light dark soliton pair only experiences attractive forces when their mutual separation is sufflciently small （〈 60 μm）, and the degree of the attraction depends on their mutual separation and their arrangement direction. When the separation is larger than 60 μm, the interaction is not evident.
