Abstract
The authors give the theory of optical Faraday rotation and circular dichroism for a transition of mixed magnetic-dipole and electric-quadrupole character in the presence of hyperfine structure. The results are applied to two transitions of atomic bismuth, lambda 647.6 nm (Jj=3/2 to Jj=5/2) and lambda 875.5 nm (Jj=3/2 to Jj=3/2). They have studied the Faraday rotation profiles of these lines under high resolution; the results confirm the theoretical predictions and for each transition give a value for the ratio, chi , of the electric-quadrupole and magnetic-dipole reduced matrix elements, (Jj//( omega /4 square root 3)(-2er2C(2))//Ji) and (Jj// mu //Ji). They obtain chi =-0.60(2) for lambda 647.6 nm and chi =+0.13(7) for lambda 875.5 nm, to be compared with the theoretical values -0.65 and +0.11 respectively.
