We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of 197Au with beam momentum of 11.5A GeV/c on targets of 208Pb and 197Pt. The yields are reported for nuclei with baryon number A = 1 up to A = 7, and typically cover a rapidity range from y c.m. to y c.m. + 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.

Abstract
We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of 197Au with beam momentum of 11.5A GeV/c on targets of 208Pb and 197Pt. The yields are reported for nuclei with baryon number A = 1 up to A = 7, and typically cover a rapidity range from y c.m. to y c.m. + 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.
