The mass of the glueballs is calculated in the B.S. equation framework
. Under instantaneous approximation, the wave function of B.S. equatio
ns are obtained. The kernel is chosen as the sum of an one-gluon excha
nge potential, a contact interaction and a linear confining potential.
The numerical results are in agreement with that of recent lattice ca
lculation. (C) 1998 Elsevier Science B.V.
