Abstract
The quark wavefunction in a proton has been calculated by using the global
colour symmetry model. We find that the property of this wavefunction is cl
osely related to the nonperturbative vacuum configuration. Using the wavefu
nction we make the calculation of the matrix element of the axial vector cu
rrent of the quarks in the proton ground state. Its value is found to be 0.
17, which is perfectly consistent with 0.23(+6).
