Resumen:
This Letter presents the first strong evidence for the resolution of the excited B mesons B1 and B2 astwo separate states in fully reconstructed decays to B. The mass of B1 is measured to be 5720:6 2:4 1:4 MeV=c2 and the mass difference M between B2 and B1 is 26:2 3:1 0:9 MeV=c2, givingthe mass of the B2 as 5746:8 2:4 1:7 MeV=c2. The production rate for B1 and B2 mesons isdetermined to be a fraction 13:9 1:9 3:2% of the production rate of the B meson.
