Abstract

Using the CLEO-II detector at CESR, we have observed the Ds1(2536)+ in the decay modes Ds1+→D*0K+ and D*+KS+, and measured its fragmentation and production ratios. Using the helicity angle distribution of the daugter D*0, we obtain new evidence for the assignment of 1+ for the spin and parity of the Ds1+. We also set upper limits on the decays Ds1+→Ds*+λ, D0K+ and D+Ks0.
