Description: We measure the top quark mass using approximately 359 pb-1  of data from pp&macr; collisions at   s  = 1.96 GeV at CDF Run II. We select tt&macr; candidates that are consistent with two W bosons decaying to a charged lepton and a neutrino following tt&macr; &rarr;  W+W-bb&macr; &rarr;  l+l-  nn&d1; bb&macr;. Only one of the two charged leptons is required to be identified as an electron or a muon candidate, while the other is simply a well measured track. We use a neutrino weighting algorithm which weighs each possibility of neutrino direction to reconstruct a top quark mass in each event. We compare the resulting distribution to Monte Carlo templates to obtain a top quark mass of   170.8+6.9-6.5 (stat) +/- 4.6 (syst) GeV/c 2.
