Abstract: The coupled cluster method is improved to calculate sixth order coefficients μF0,μF2 and relevant parameter ζ of glueball wave function in 2+1-D SU(2) lattice gauge theory (LGT). In the calculation,we select hollow graphs as trial wave function. The calculated results of μF0,μF2 and ζ show good scaling behaviors at weak coupling region.
