Abstract

Cross sections for

e^{+} e^{-} \to hadrons, e^{+} e^{-}, and μ^{+} μ^{-}

near 3684 MeV are presented. The

ψ (3684)

resonance is established as having the assignment

J^{PC} = 1^{- -}

. The mass is 3684 ± 5 MeV. The partial width for decay to electrons is

Γ_{e} = 2.1 \pm 0.3

keV and the total width is

Γ = 228 \pm 56

keV.
