Isospin relations are used to eliminate hadronic uncertainties in various {ital CP} asymmetries in {ital B}{sup 0} decays via {ital b}{r arrow}{ital u{bar u}s}, e.g., {ital B}{sup 0}{r arrow}{pi}{sup 0}{ital K}{sub {ital S}}. A clean measurement of the angle {alpha} of the unitarity triangle is thus made possible. The magnitudes of the tree and the penguin amplitudes can be measured.
