Abstract

We have investigated the effect of Be8 decay on nuclear temperature measurements in the 14N+Ag reaction at E/A=35 MeV. We have determined what percentage of the apparent Li7 spectrum is due to the identification of the coincident alpha particles from Be8 decay as Li7. This information, coupled with previously published temperature measurements, produces agreement between temperatures obtained from Li7 excited state populations and those obtained from Be7 excited state populations. Additionally, we measured the production of the excited states of Li7 and Be7 nuclei emitted from the same reaction at beam energies of E/A=20 MeV and E/A=25 MeV. The temperatures extracted from these excited state populations are consistent with one another when corrected for the Be8 contamination of the Li7 spectra.
