Studies of the interference effect in the mixed-type forbidden line 461.5 nm are reported. A special computer program considering the M1-E2 interference was designed to obtain the predicted contour of the Zeeman structure of the line. By variation of free parameters, describing the line shape and the electric-quadrupole admixture, the calculated profiles were fitted into the recorded spectra. The E2 admixture found is (7.4± 0.4)%. Our result is compared with recent theories and other experiments.
