Understanding proton emission in central heavy-ion collisions

Two-proton correlation functions for central collisions of {sup 36}Ar+{sup 45}Sc at {ital E}/{ital A}=80, 120, and 160 MeV are compared to calculations with the Boltzmann-Uehling-Uhlenbeck (BUU) transport model. Agreement is found at {ital E}/{ital A}=80MeV, but the model predicts too large correlat...

Zusammenfassung:	Two-proton correlation functions for central collisions of {sup 36}Ar+{sup 45}Sc at {ital E}/{ital A}=80, 120, and 160 MeV are compared to calculations with the Boltzmann-Uehling-Uhlenbeck (BUU) transport model. Agreement is found at {ital E}/{ital A}=80MeV, but the model predicts too large correlations at {ital E}/{ital A}=120 and 160 MeV. The discrepancy may be due to delayed emission of protons from particle-unstable states not modeled in BUU. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
