We report measurements from experiment E864 at the BNL-AGS of the yields of particle unstable light nuclei in central collisions of 197Au with beam momentum of 11.5 A GeV/c on 197Pt. Yields are reported as a function of rapidity for the nuclei 4H, 4Li, 5He, and 5Li in the rapidity range from y c.m. to y c.m. + 0.8 and in the transverse momentum range of approximately 0.1 ≤ p T/A ≤ 0.4 GeV/c. The yields are compared to previously reported yields and trends for the production of stable light nuclei. The nonobservation of two excited states 5He* 16.75 MeV and 5Li* 16.66 MeV is used to set an upper limit on the yields of these stales.

Abstract
We report measurements from experiment E864 at the BNL-AGS of the yields of particle unstable light nuclei in central collisions of 197Au with beam momentum of 11.5 A GeV/c on 197Pt. Yields are reported as a function of rapidity for the nuclei 4H, 4Li, 5He, and 5Li in the rapidity range from y c.m. to y c.m. + 0.8 and in the transverse momentum range of approximately 0.1 ≤ p T/A ≤ 0.4 GeV/c. The yields are compared to previously reported yields and trends for the production of stable light nuclei. The nonobservation of two excited states 5He* 16.75 MeV and 5Li* 16.66 MeV is used to set an upper limit on the yields of these stales.File in questo prodotto:
