Query: Effect of Density Correlations on the Coherency of Relativistic Bunch
  Radiation   The coherent radiation of the electron beam with account of particle position
correlations because of strong Coulomb interaction is considered. For the first
time it is shown that the coherency of the radiation of the bunch with account
of correlations depend on the mean inter particle distance (mean density of the
bunch). The conditions of coherency are found. The influence of deviations from
mean distance on the radiation coherency is considered.
