The authors present a study of the decays B{sup -} --> D*{sup 0}{pi}{sup -} and B{sup -} --> D*{sup 0}K{sup -}, where the D*{sup 0} decays into D{sup 0}{pi}{sup 0}, with the D{sup 0} reconstructed in the CP eigenstates K{sup -}K{sup +} and {pi}{sup -}{pi}{sup +} and in the (non-CP) channels K{sup -}{pi}{sup +}, K{sup -}{pi}{sup +}{pi}{sup +}{pi}{sup -}, and K{sup -}{pi}{sup +}{pi}{sup 0}. They use an unbinned maximum likelihood fit to measure the signal yields. Using a sample of about 123 million {Upsilon}(4S) decays into B{bar B} pairs, they measure the ratios of decay rates.
