Abstract
We report measurements of the electric dipole matrix elements of the and transitions. Each of these determinations is based on direct, precise comparisons of the absorption coefficients between two absorption lines. For the matrix element, we measure the ratio of the absorption coefficient on this line to that of the transition . The matrix element of the line has been determined previously with high precision by many groups. For the matrix element, we measure the ratio of the absorption coefficient on this line to that of the transition. Our results for these matrix elements are and . These measurements have implications for the interpretation of parity nonconservation in atoms.
