| 摘 要： | Wave function is important for determining decay constants fDS- and fD-. Using the 5 types of D meson wave functions in the heavy quark limit, we studied the uncertainties of radiative pure-leptonic decays of DS-(D-) mesons. The branching ratios are (1.025390—1.706812) × 10-5 and (0.953498—1.576725) × 10-6 for DS- and D- decays, respectively, which are sensitive to the type of wave function.
