We analyze the invariant mass spectrum of A-A in I~C(K-, K+AA) reaction at PK-= 1.65 GeV/c by using a combined framework of IntraNuclear Cascade (INC) model and the correlation function technique. The observed enhancement at low-invariant masses can be well reproduced with attractive A-A interactions with the scattering length either in the range a = -6 ,,, -4 fm (no bound state) or a = 7 ,-~ 12 fm (with bound state). We also discuss A-A correlation functions in central relativistic heavy-ion collisions as a possible way to eliminate this discrete ambiguity.
