Nuclear temperatures and the population of particle-unstable states ofLi6ininduced40reactions onAu197atE/A=60MeV

Correlations between coincident alpha particles and deuterons emitted in ${}_{}{}^{40}{}_{}{}^{}\mathrm{induced}$ reactions on ${}_{}{}^{197}{}_{}{}^{}\mathrm{Au}$ at E/A=60 MeV were measured. The relative populations of particle-unstable states of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ were extracted. The measured spectra are consistent with a mean nuclear temperature at emission of T=5 MeV. Limitations of temperature measurements via the population of excited states are discussed.
