NUCLEAR TEMPERATURE-MEASUREMENTS WITH HELIUM-ISOTOPES

Temperatures extracted with the family of (He-3, He-4) isotope ratio t hermometers, T-He, have been studied and cross-checked with temperatur es, T(He-4) constructed from excited and ground state populations of He-4. Empirical correction factors provide baseline corrections for se quential decay effects for T-He < 4.5 MeV, independent of projectile, target and incident energies. After corrections for fluctuations due t o sequential decay, statistical calculations predict that T-He, and T( He-4) should agree. (C) 1998 Published by Elsevier Science B.V. All r ights reserved.
