Abstract
From an analysis of the ionisation energy loss
of charged particles selected from
110326 e+e-
candidates recorded by the OPAL
detector at e+e- centre-of-mass energies near the
Z0 resonance,
we determine the one-prong tau decay branching ratios:
Br
=
=
where the notation refers to
a

,
and where the first
uncertainty is statistical and the second is systematic.
