  Small-angle, two-particle correlation functions have been measured for 36Ar+
112,124Sn collisions at E/A = 61 MeV. Total momentum gated neutron-proton (np)
and proton-proton (pp) correlations are stronger for the 124Sn-target. Some of
the correlation functions for particle pairs involving deuterons or tritons
(nd, pt, and nt) also show a dependence on the isospin of the emitting source.
