We study the semileptonic decays B±→ n (1)lv, which are suggested to be used to extract the hadronic form factors of B meson decays to n(n′) and the angle of n-n′ mixing. This would be of great benefit to theoretical studies of B nonleptonic decays involving n and n′, and could lead to a reliable and complementary determination of Vub. The branching ratios are estimated to be B(B±→n(')lv) = 4.32 ±0.83 (2.10±0.40) × 10-5, which could be extensively studied experimentally at BaBar and Belle.
