Effect of the finite size of a nucleus having a magnetic dipole moment on pair photocreation with an account of particle polarization

The angular distribution and longitudinal polarization of electron-positron pairs formed by circularly polarized photons in the field of a nucleus having a magnetic dipole moment are found in the Born approximation with an account of the mean­ square radius and force moment of the nuclear charge and magnetic-moment distribu­ tions. The effects of <r^2> and <r^4> on the spectra of charge and magnetic pair photocreation are steady.
