Title: Measurements of light nuclei production in 11.5A GeV/c Au+Pb heavy-ion collisions

Abstract

We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of {sup 197}Au with beam momentum of 11.5A GeV/c on targets of {sup 208}Pb and {sup 197}Pt. The yields are reported for nuclei with baryon number A=1 up to A=7, and typically cover a rapidity range from y{sub c.m.} to y{sub c.m.}+1 and a transverse momentum range of approximately 0.1{<=}p{sub T}/A{<=}0.5 GeV/c. We calculate coalescence scale factors B{sub 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. (c) 2000 The American Physical Society.
