Abstract
Static polarizabilities of the low-lying 1/2(+) baryons are studied wi thin the collective coordinate approach to the three flavor generaliza tion of the Skyrme model; in particular, magnetic polarizabilities are considered. Predicted polarizabilities, which result from different t reatments of the strange degrees of freedom in this model, are critica lly compared, Their deviations from the flavor symmetric formulations are discussed.
