Coyne, D G

The use of the Crystal Ball detector for the study of e/sup +/e/sup -/ annihilations near charm threshold - at the psi(3097), psi'(3685), psi'(3770) and in the continuum 3770 less than or equal to ..sqrt..s less than or equal to 4500 MeV - is discussed. This paper will concentrate on the special techniques available to the Crystal Ball which allow measurement of inclusive ..gamma.., ..pi../sup 0/ and eta cross sections. Preliminary results for these processes at particular center of mass energies are presented. An update of the inclusive and exclusive evidence for the eta/sub c/(2980), for the sake of completeness, is given in the Appendix.
