    "abstract": "We calculate the equation of state of a Fermi gas with resonant interactions\nwhen the effective range is appreciable. Using an effective field theory for\nlarge scattering length and large effective range, we show how calculations in\nthis regime become tractable. Our results are model-independent, and as an\napplication, we study the neutron matter equation of state at low densities of\nastrophysical interest 0.002 fm^{-3} \u003c rho \u003c 0.02 fm^{-3}, for which the\ninterparticle separation is comparable to the effective range. We compare our\nsimple results with those of conventional many-body calculations.",
