HYPERON FORM-FACTORS IN THE SKYRME MODEL

The vertex function of the kaon-nucleon-hyperon is calculated in the f ramework of the Skyrme model for the off-shell region of the kaon. The axial charge transition radius is deduced from the vertex function an d compared to the calculations of other models. It turns out that the axial properties of the hyperon in the Skyrme model are not very satis factory as in the case of the nucleon. We discuss the possibilities of remedy by alluding to the presence of the Casimir effect.
