We have used recent polarized deep-inelastic scattering data from CERN and
SLAC to extract information about nucleon spin structure. We find that the SMC
proton data, the E142 neutron data and the deuteron data from SMC and E143 give
different results for fractions of the spin carried by each of the
constituents. These appear to lead to two different and incompatible models for
the polarized strange sea. The polarized gluon distribution occuring in the
gluon anomaly does not have to be large in order to be consistent with either
set of experimental data. However, it appears that the discrepancies in the
implications of these data cannot be resolved with any simple theoretical
arguments. We conclude that more experiments must be performed in order to
adequately determine the fraction of spin carried by each of the nucleon
constituents.Comment: 23 page
