Abstract

We present cross sections for

e^{+} e^{-} \to hadrons

,

e^{+} e^{-}

, and

μ^{+} μ^{-}

near 3095 MeV. The

ψ (3095)

resonance is established as having an assignment

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

. The mass is 3095 ±4 MeV. The partial width to electrons is

Γ_{e} = 4.8 \pm 0.6

keV and the total width

Γ = 69 \pm 15

keV. Total rates and interference measurements for the lepton channels are in accord with

μ - e

universality.
