A method is proposed for tagging the flavor of neutral B mesons in the
study of CP-violating decay asymmetries. The method makes use of a possible
difference in interactions in Bπ or B∗π systems with isospins 1/2
and 3/2, and would be particularly clean if the I=1/2 systems can be
detected as ``B∗∗'' resonances.Comment: Submitted to Phys. Rev. D. 11 pages, LaTeX, Technion-PH-92-40 / PITHA
