Query: Momentum distribution functions and pair correlation functions of
  unpolarized uniform electron gas in warm dense matter regime   In this paper we continued our research of the uniform electron gas, using
the single--momentum path integral Monte Carlo method, and studied the momentum
distribution functions and the pair correlation functions in the warm dense
matter regime. We discovered that the single--particle momentum distribution
function deviates from the Fermi distribution and forms so-called "quantum
tails" at high momenta, if non-ideality is strong enough in both degenerate and
non-degenerate cases. This effect is always followed by the appearance of the
short--range order on the pair distribution functions and can be explained via
the tunneling through the effective potential wells surrounding the electrons.
Also we calculated the average kinetic and potential energies in the wide range
of states, expanding our previous results significantly.
