The data of electric quadrupole (E2) and magnetic dipole (M1) transitions among the levels of the ground configuration can be used for diagnostics of thermonuclear plasmas or for the estimation of the radiative losses in plasmas (Karwowski and Martin, 1991).
The electric quadrupole consists of two equal and opposite dipoles displaced from each other by another infinitesimal distance [e.
