Description
It is shown that the flavour dependence of the matrix elements of the anomalous divergence and the flavour dependence of the matrix elements of the pseudoscalar quark bilinears correspond to each other. This can be used to define flavour independent matrix elements of the anomalous divergence, which are related to the axial U(1) charge and to the spin densities inside the nucleon. (orig.)
