We have observed the decay ψ(3684)→ψ(3095)η with a branching fraction of (4.3±0.8)%. This measurement, together with previous measurements of ψ(3684)→ψ(3095)+anything, ψ(3684)→ψ(3095)π+π-, and ψ(3684)→ψ(3095)γγ, indicates that isospin is conserved in the decay ψ(3684)→ψ(3095)ππ and establishes the isospin and G parity of the ψ(3684) to be IG=0-.
