| dc.description | This report concerns the energy of neutron-matter for densities below $0.15 fm^{-3}$ and temperatures at and below $10 MeV$. Separable NN-interactions are obtained by inverse scattering from the experimental phase-shifts with specified momentum cut-offs $Λ$. Results of Brueckner-Bloch-DeDomicis as well as finite temperature Green's function calculations show independence of cut-off for $Λ\geq 3$. Agreement with the low-density virial expansion is found. Results of Hartree-Fock as well as second order calculations show considerable $Λ$-dependence and the agreement with the virial expansion is lost. The "best" first-order choice of $Λ$ is found to be $\sim 2.5 fm^{-1}$, which agrees with $V_{low k}$ studies. Reasonable agreement between the second order and the Brueckner results is also found for this value of $Λ$ except at low density. Only 2-body forces are used in this study. | |
