Abstract

We present here a measurement of six branching ratios of

ψ (3095)

corresponding to the decays

ψ (3095) \to ρ π

,

2 (π^{+} π^{-})

,

2 (π^{+} π^{-}) 1 π^{0}

,

3 (π^{+} π^{-})

,

3 (π^{+} π^{-}) 1 π^{0}

, and

4 (π^{+} π^{-}) 1 π^{0}

. From this study, the isospin and

G

-parity quantum numbers are found to be

I^{G} = 0^{-}

.
