Production and decay of the Ds1 (2536)+
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+Ks 0. © 1993.
