英文摘要	Using 462 fb(-1) of e(+)e(-) annihilation data recorded by the Belle detector, we report the first observation of the decay D(s1)(2536)(+)-> D(+)pi(-)K(+). The ratio of branching fractions B(D(s1)(2536)(+)-> D(+)pi(-)K(+))/B(D(s1)(2536)(+)-> D(+)K(0)) is measured to be (3.27 +/- 0.18 +/- 0.37)%. We also study the angular distributions in the D(s1)(2536)(+)-> D(+)K(S)(0) decay and measure the ratio of D- and S-wave amplitudes. The S-wave dominates, with a partial width of Gamma(S)/Gamma(total)=0.72 +/- 0.05 +/- 0.01.
