Conversion electron measurements with an electrostatic spectrometer proved the existence of the 1,565 __ 6 eV transition in 2~The conversion intensity ratios, N1/N2 = 1.2+0.2, NI/N3 = 1.1 +0.2, N2/N3 =0.92_+0.15, N4/N3=0.03+O.02 and Ns/N3 =0.04 _+ 0.02 were determined. These values agree with our calculations for the M 1 + E2 multipolarity with the E 2/M 1 mixing ratio 62= (1.1 _+ 0.3) x 10-4 and exclude all pure multipolarities with L__<4. The total conversion coefficient for the above M1 +E2 mixture was evaluated to be (4.7_+0.7)x 104. The reduced B(M 1, 1/2 ~ 3/2) probability was derived to be (3.9_+ 1.2)x 10 .3 (eh/2Mc) 2. The natural widths of the N-subshell conversion lines in mercury were found to be F(N 0 = 8.3 _+ 1.5, F(N2)= 5.8 _+ 1.5 and F(N3)= 6.5 _+ 1.0 eV, Monte Carlo calculations of electron scattering in matter yielded the conversion line shapes in qualitative agreement with the experiment.
