Abstract：
By Solving Shrodinger equation with the RPA coupled cluster method, The higher order glueball wave function in 2+1-D SU(2) lattice gauge theory is calculated. In the calculation, hollow Wilson graphs are selected as the trial wave function, and special Wilson graphs are treated approximately. The sixth and the seventh order results for the coefficients μ0F andμ2F and the relevant parameterζ of the glueball wave function show good scaling behaviors at weak coupling region(β=4.8--9.6 ). The seventh order vacuum energy curve is in agreement with the sixth order ones for in the coupling region of β=0.8-8.8 .
