Measurements of light nuclei production in $11.5A\mathrm{GeV}/c$ Au+Pb heavy-ion collisions

We report on measurements by the E864 experiment at the BNL-AGS of the yields of light nuclei in collisions of ${}^{197}\mathrm{Au}$ with beam momentum of $11.5A\mathrm{GeV}/c$ on targets of ${}^{208}\mathrm{Pb}$ and ${}^{197}\mathrm{Pt}.$ The yields are reported for nuclei with baryon number $A=1\mathrm{}$ up to $A=7,$ and typically cover a rapidity range from $y_{\mathrm{c}.\mathrm{m}.\mathrm{}}$ to $y_{\mathrm{c}.\mathrm{m}.\mathrm{}}+1\mathrm{}$ and a transverse momentum range of approximately $0.1<~p_T/A<~0.5\mathrm{GeV}/c.\mathrm{}$ 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.
