Numerical values of the exchange‐correlation contributions of the pressure, the free energy and the chemical potential are obtained for hydrogen at any degree of degeneracy. The evaluations are performed with the RPA‐dielectric function for the Montroll‐Ward contribution by integration over real frequencies. The influence of the proton degeneracy is analyzed for increasing degeneracy of the electrons. A comparison with the correlation part of the free energy and of the chemical potential without proton degeneracy is given.
