| Abstract: | We present a fit to spin asymmetries which gives polarized quark distributions. These functions are closely related to the
ones given by the Martin, Roberts and Stirling fit for unpolarized structure functions. The integrals of polarized distributions
are discussed and compared with the corresponding quantities obtained from neutron and hyperonβ-decay data. We use the combination of proton, neutron and deuteron spin asymmetries in order to determine the coefficients
of our polarized quark distributions. Our fit shows that phenomenologically there is no need for taking polarized gluons into
account.
