Abstract

In a study of 2.7 million J decays with the Mark III, a new magnetic detector at SPEAR, we have observed the sequential decay Jc, c. The product branching fraction is (1.02±0.25±0.14)×10-4, where the quoted errors are statistical and systematic, respectively. Analysis of the final-state angular distributions provides the first experimental determination that the spin and parity of the c are 0-.
