| 英文摘要 | Clustering in low density nuclear matter has been investigated using the NIMROD multidetector at Texas A&M University. Thermal coalescence modes were employed to extract densities, rho, and temperatures, T, for evolving systems formed in collisions of 47A MeV Ar-40 + Sn-112, Sn-124 and Zn-64 + Sn-112, Sn-124. The yields of d, t, He-3, and He-4 have been determined at rho = 0.002 to 0.03 nucleons/fm(3) and T = 5 to 11 MeV. The experimentally derived equilibrium constants for alpha 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. |
