Rajabi, M. Modarres] The lowest order constrained variational (LOCV) and the extended LOCV (ELOCV) method in the frame work of the Ristig-Clark formalism is used to calculate the density dependence of the normal liquid helium 3 one-body momentum distribution, n(k), at zero and finite temperatures. We impose the familiar 6-12 Lennard-Jones potential as the inter-atomic interaction. It is shown that the normal liquid helium 3 one-body momentum distribution, n(k), decreases at low momentums by increasing the density, but its tail becomes longer. The discontinuity of n(k) also decreases as we increase the density of the normal liquid helium 3. The discontinuity disappears at finite temperature but the same density dependent is observed as that of frozen case.
