Neutrino-pair bremsstrahlung rate is calculated in the framework of the Weinberg-Salam theory for the dense matter relevant to the interior of white dwarfs and neutron stars. Ionic correlations both in the liquid state and in the bcc lattice state have been taken into account accurately. It is found that the ionic correlation in the liquid state reduces the neutrino-pair bremsstrahlung rate typically by a factor 2–20 depending on the element and temperature. It is also found that accurate inclusion of the Debye-Waller factor reduces the neutrino-pair bremsstrahlung rate in the lattice state typically by a factor 2.
