We treat the baryon as a composite system made out of a ''core'' of th
ree quarks (as in the standard quark model) surrounded by a ''sea'' (o
f gluons and q (q) over bar-pairs) which is specified by its total qua
ntum numbers like flavor, spin and color. Specifically, we assume the
sea to be a flavor octet with spin 0 but no color. The general wavefun
ction for spin 1/2 baryons with such a sea component is given and an a
pplication to the magnetic moments is considered. Numerical analysis s
hows that the scalar sea can provide a good fit to the magnetic moment
data using experimental errors.
