The branching fractions from the excited state 6P1/2 of singly charged barium ion has been measured with a precision 0.03% in an ion trap experiment. This measurement along with the known value of the upper state lifetime allowed the determination of the dipole matrix elements for the transitions P\text\ensuremath-S and P\text\ensuremath-D to below the 1% level. Therefore, it is now possible to compare the many-body calculations of these matrix elements at a level which is of significance to any parity-nonconservation experiment on barium ion. Moreover, these dipole matrix elements are the most significant contributors to the parity-violating matrix element between the S\text\ensuremath-D transition, contributing up to 90% to the total. Our results on the dipole matrix elements are 3.305\ifmmode±\else\textpm\fi0.014 a.u. and 3.042\ifmmode±\else\textpm\fi0.016 a.u. for the S\text\ensuremath-P and P\text\ensuremath-D transitions, respectively.
