Abstract
We have studied semileptonic B decay to the exclusive charmless states π, ρ/ω, η and η′ using the full 15.5fb-1 CLEO Υ(4S) sample, with measurements performed in subregions of phase space to minimize dependence on a priori knowledge of the form factors involved. We find total branching fractions B(B0→π-+ν)=(1.37±0.15stat±0. 11sys)×10-4 and B(B0→ρ-+ν)=(2.93±0.37stat±0. 37sys)×10-4. We find evidence for B+→η′+ν, with B(B+→η′+ν)=(2.66±±0.80stat±0.56sys) ×10-4 and 1.20×10-4
