Abstract
The long-term interaction of two unlike spirals is studied in the fram ework of the Belousov-Zhabotinsky reaction. Both repulsive and attract ive interactions have been observed for different initial distances be tween spirals. We describe how a spiral pair can evolve in three diffe rent ways; namely, spirals attract each other, collide, and annihilate ; spirals repel each other and one of them dominates; and, finally, bo th spirals coexist without dominance of one of them.
