We calculate the characteristics of the state $2p^{-2}(^3P)3s3p^1P$ in the resonant photoionization cross section of the neon atom, using the diagonalization approximation on the basis of Hartree-Fock functions. The direct coupling of the "particle-hole" state and "two particles - two holes" states is taken into account by introducing an empirical parameter. The results are compared with experiment and with the results of calculations by the method of strong coupling between channels.
