A new method to extract the weak phase γ is suggested by exploiting B
---> D K^{(*)} decay modes that are not Cabibbo suppressed, using the isospin
relations, and ignoring the annihilation diagram as usual. Assuming 3×108BBˉ pair at B factories, one can determine γ with
3−σ accuracy for 80^o D K modes and for
50^o D K^* modes.Comment: 10 pages with 2 figure
