Matrix elements of the form <0|tr g2GG|G> are calculated using the lattice QCD Monte Carlo method. Here, |G> is a glueball state with quantum numbers 0++, 2++, 0-+ and G is the gluon field strength operator. The matrix elements are obtained from the hybrid correlation functions of the fuzzy and plaquette operators performed on the 124 and 144 lattices at β = 5.9 and 5.96 respectively. These matrix elements are useful in the calculation of the partial widths of J/ψ radiative decays into glueballs.
