摘要：

The process of nu<(nu)over bar> radiation due to interaction of electrons with phonons in the crust of a cooling neutron star is studied with the consistent account of an electromagnetic coupling between electrons in the medium. The wavelength of radiated neutrinos and antineutrinos is typically much larger than the electron Debye screening distance in the medium, and therefore plasma polarization substantially modifies the effective weak current of the electron. Is shown, that under above conditions plasma polarization screens totally a vector weak interaction of the electron with a neutrino field. As a result, the vv emissivity is less in approximately 2.23 times than previously estimated. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
