We measure the branching fraction of the top quark to longitudinally and right-handed polarized $W$ bosons, $F_0$ and $F_+$, using approximately 200 pb$^{-1}$ of $\bar{p}p$ collisions collected by the CDF II detector. We analyze two quantities sensitive to the $W$ helicity: the invariant mass of the charged lepton and the bottom-quark jet in the decay $t\to Wb \to \ell��b$ (where $\ell=e$ or $��$), and the transverse momentum of the charged lepton. We find $F_0=0.74^{+0.22}_{-0.34}$, and $F_+, 7 pages, 4 figures, submitted to Physical Review Letters
