  We have used the Australia Telescope Compact Array to image the neutral
hydrogen in the merging system NGC 3256, to test the idea that globular
clusters (GC) form during the interactions and mergers of disk galaxies. We
compare our observations with hydrodynamical numerical simulations, from the
literature, to examine the hypothesis that the H I fragments with masses
greater than 10$^{7\pm1} \mo$ are sites of GC formation. We appear to have
detected detached H I fragments in the vicinity of NGC 3256. These fragments,
with masses ~10^7 solar masses, may have little dark matter content which is
also a characteristic of globular clusters, and so our observations support the
hypothesis that globular clusters form in the type of interaction that resulted
in NGC 3256.
