Momentum distributions are presented for liquid /sup 3/He based on ground-state trial functions of Jastrow-Slater type. The calculations are performed within the framework of the diagrammatic cluster approach of Ristig and Clark, using Zabolitzky's results for the static structure function in the Fermi hypernetted-chain approximation. Sensitivity of the depletion of the Fermi sea to the assumed two-body correlation function is studied. Comparison is made with a momentum distribution determined by Ceperley, Chester, and Kalos using a Fermi Monte Carlo procedure.
