We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of Au(197) with beam momentum of 11.5 A GeV/c on targets of Pb(208) and Pt(197). The yields are reported for nuclei with baryon number A=1 up to A=7, and typically cover a rapidity range from y(cm) to y(cm)+1 and a transverse momentum range of approximately 0.1 < p(T)/A < 0.5 GeV/c. We calculate coalescence scale factors B(A) from which we extract model dependent source dimensions and collective flow velocities. We also examine the dependences of the yields on baryon number, spin, and isospin of the produced nuclei.

Cosmic rays, anti-helium, and an old navy spotlight
astro-ph.HE 2017-04 conditional novelty 7.0 of 10

Secondary cosmic-ray anti-helium production is estimated to be 10 to 100 times higher than earlier predictions, using a coalescence scaling law calibrated by HBT interferometry, potentially detectable by AMS-02.

nucl-ex 2026-07 conditional novelty 6.0 of 10

Isobar collision yields of ³_ΛH and light nuclei favor coalescence with non-Gaussian hypertriton wave functions that carry enhanced short-distance d–Λ probability, inconsistent with a Gaussian ansatz tied to the measu...

Deuteron, triton, helium-3 and antinucleus yields in pp collisions from 0.9 to 7 TeV show the coalescence parameter rising with transverse momentum, a trend not seen in earlier lower-energy data.
Production of light nuclei and anti-nuclei in pp and Pb-Pb collisions at LHC energies

Deuteron and helium-3 yields in Pb-Pb collisions at 2.76 TeV follow the same chemical freeze-out temperature (about 156 MeV) as ordinary hadrons, and their ratios stay constant with centrality, favoring density-driven...
Light nucleus and hypernucleus production at RHIC and LHC energies: a comparative study of phenomenological models

A community task-force review concludes that statistical hadronization, coalescence, and transport models each reproduce parts of the light-nucleus data, but existing measurements cannot yet distinguish them.
