By carrying out extensive lattice regularized diffusion Monte Carlo calculations, we study the spin and density dependence of the ground-state energy for a quasi-one-dimensional electron gas, with harmonic transverse confinement and long-range 1/ r interactions. We present a parametrization of the exchange–correlation energy suitable for spin density functional calculations, which fulfils exact low and high density limits.
