With two anisotropic lattices, the mutlipole amplitudes E\_1(0), M\_2(0) and E\_3(0) are obtained to be 0.114(12)GeV, -0.011(5)GeV and 0.023(8)GeV, respectively. Thus the partial decay width \$\Gamma(J/\psiG\_2^++)\$ is estimated to be 0.99(22)keV which corresponds to a large branch ratio 1.1(2)x10^-2. The phenomenological implication of this result is also discussed.
