  This is the second of two papers which investigate cold dilute neutron matter
on the lattice using pionless effective field theory. In the unitary limit,
where the effective range is zero and scattering length is infinite, simple
scaling relations relate thermodynamic functions at different temperatures.
When the second virial coefficient is properly tuned, we find that the lattice
results obey these scaling relations. We compute the energy per particle,
pressure, spin susceptibility, dineutron correlation function, and an upper
bound for the superfluid critical temperature.
