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 $A=1$ up to $A=7,$ and typically cover a rapidity range from ${y}_{\mathrm{c}.\mathrm{m}.}$ to ${y}_{\mathrm{c}.\mathrm{m}.}+1$ and a transverse momentum range of approximately $0.1&lt;~{p}_{T}/A&lt;~0.5\mathrm{GeV}/c.$ 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.
