Abstract (data abstract)
Fermilab-Collider. Measurement of the inclusive cross sections times branching fractions into electrons for W+- and Z0 bosons produced in PBAR P collisions at c.m. energy 1800 MeV (a smaller sample gives the cross sections at 630 GeV). The data were taken during the 1994-95 running period and have an integrated luminosity of 84.5 pb-1. The ratio of the cross sections is determined. Combining these data with the 1992-93 data gives a W boson width of 2.152 +- 0.066 GeV and a 95 pct C.L. upper limit of the invisible W width of 0.191 GeV.
