  We perform calculations of the {3D} finite-temperature homogeneous electron
gas (HEG) in the warm-dense regime ({r_{s} \equiv (3/4\pi n)^{1/3}a_{B}^{- 1} =
1.0- 40.0} and {\Theta \equiv T/T_{F} = 0.0625- 8.0}) using restricted path
integral Monte Carlo (RPIMC). Precise energies, pair correlation functions, and
structure factors are obtained. For all densities, we find a significant
discrepancy between the ground state parameterized local density approximation
(LDA) and our results around {T_{F}} . These results can be used as a benchmark
for improved functionals, as well as input for orbital-free DFT formulations.
