The decay psi (3684) ..-->..psi (3095) eta has been observed to have a branching fraction of (4.3+-0.8) %. This measurement, together with previous measurements of psi (3684) ..-->..psi (3095)+ anything, psi (3684) ..-->..psi (3095) ..pi../sup +/..pi../sup -/, and psi (3684) ..-->..psi (3095) ..gamma gamma.., indicates that isospin is conserved in the decay psi (3684) ..-->..psi (3095) ..pi pi.. and establishes the isospin and G parity of the psi (3684) to be I/subG/=0/sup -/.
