We perform a Monte Carlo calculation of the second moment of the polarised valence quark distributions in the nucleon, using quenched Wilson fermions. The special feature of this moment is that it is directly accessible experimentally. At a scale of mu approximate to 2GeV we find Delta((1))u = 0.198(8), Delta((1))d = -0.0477(33). We compare these numbers with recent experimental results of the SMC collaboration. (C) 1997 Elsevier Science B.V.
