摘要：

We have studied the exclusive semileptonic decay mode D+ --> K0BAR e + v(e) in the Fermilab photoproduction experiment E691. We find the ratio B(D+ --> K0BAR e + v(e))/B(D+ --> K- pi+ pi+) to be 0.66 +/- 0.09 +/- 0.14, corresponding to a D+ --> K0BAR e + v(e) branching ratio of (6.1 +/- 0.9 +/- 1.6)%. Combining this result with our measurement of the D+ lifetime, we find GAMMA(D+ --> K0BAR e + v(e)) = (5.6 +/- 0.8 +/- 1.5) x 10(10) s-1. We also find, using E691 averages, the ratio of decay rates GAMMA(D --> K* ev)/GAMMA(D --> Kev) to be 0.55 +/- 0.14.
