Title: Measurement of {gamma}{sub ee}(J/{psi}), {gamma}{sub tot}(J/{psi}), and {gamma}{sub ee}[{psi}(2S)]/{gamma}{sub ee}(J/{psi})

Abstract

Using data acquired with the CLEO detector at the CESR e{sup +}e{sup -} collider at {radical}(s)=3.773 GeV, we measure the cross section for the radiative return process e{sup +}e{sup -}{yields}{gamma}J/{psi}, J/{psi}{yields}{mu}{sup +}{mu}{sup -}, resulting in B(J/{psi}{yields}{mu}{sup +}{mu}{sup -})x{gamma}{sub ee}(J/{psi})=0.3384{+-}0.0058{+-}0.0071 keV, {gamma}{sub ee}(J/{psi})=5.68{+-}0.11{+-}0.13 keV, and {gamma}{sub tot}(J/{psi})=95.5{+-}2.4{+-}2.4 keV, in which the errors are statistical and systematic, respectively. We also determine the ratio {gamma}{sub ee}[{psi}(2S)]/{gamma}{sub ee}(J/{psi})=0.45{+-}0.01{+-}0.02.
