Abstract
Clustering in low density nuclear matter has been investigated using the NIMROD multi-detector at Texas A&M University. Thermal coalescence modes were employed to extract densities, , and temperatures, , for evolving systems formed in collisions of 47 MeV Ar + Sn,Sn and Zn + Sn, Sn. The yields of , , He, and He have been determined at = 0.002 to 0.032 nucleons/fm and = 5 to 10 MeV. The experimentally derived equilibrium constants for particle production are compared with those predicted by a number of astrophysical equations of state. The data provide important new constraints on the model calculations.
