摘要：

Using a high-resolution silicon vertex detector we have observed a very clean signal of 127 D*+. After a careful study of the experimental resolution of our apparatus we have measured m(D*+)-m(D0) = 145.39 +/- 0.06 +/- 0.03 MeV. We have also obtained a 90% CL upper limit to GAMMA(D*+) of 131 keV.
