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 11.5AGeV/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 yc.m. to yc.m.+1 and a transverse momentum range of approximately 0.1<~pT/A<~0.5GeV/c. We calculate coalescence scale factors BA 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.Received 6 January 2000DOI:https://doi.org/10.1103/PhysRevC.61.064908©2000 American Physical Society
