摘要：

Final-state interactions in Kee enhance the "I=(1/2 amplitude and suppress the "I=(3/2 one. The effect appears to be about an order of magnitude in the ratio of the rates and may be useful in reconciling the outstanding discrepancy between short-distance QCD corrections and experiment. © 1990 The American Physical Society.
