The Gronau-London-Wyler method extracts the Cabibbo-Kobayashi-Maskawa angle {gamma} by measuring B{sup {plus_minus}} decay rates involving D{sup 0}/{anti D}{sup 0} mesons. {ital CP} violation can be greatly enhanced for decays to final states common to both D{sup 0} and {anti D}{sup 0} that are not {ital CP} eigenstates. Large asymmetries are possible for final states f such that D{sup 0}{r_arrow}f is doubly Cabibbo suppressed while {anti D}{sup 0}{r_arrow}f is Cabibbo allowed. The measurement of interference effects in such modes allows the {ital clean} extraction of {gamma}. {copyright} {ital 1997} {ital The American Physical Society}
