This Letter presents the first strong evidence for the resolution of the excited B mesons B(1) and B∗(2) as two separate states in fully reconstructed decays to B(+)(*)π−. The mass of B(1) is measured to be 5720.6±2.4±1.4 MeV/c(2) and the mass difference ΔM between B∗(2) and B(1) is 26.2±3.1±0.9 MeV/c(2), giving the mass of the B∗(2) as 5746.8±2.4±1.7 MeV/c(2). The production rate for B(1) and B∗(2) mesons is determined to be a fraction (13.9±1.9±3.2)% of the production rate of the B(+) meson.
