*Pionic and Hidden-Color, Six-Quark Contributions to the Deuteron b1 
Structure Function *

The b1 structure function is an observable feature of a spin-1 system 
sensitive to non-nucleonic
components of the target nuclear wave function. The contributions of 
exchanged pions in the
deuteron are estimated and found to be of measurable size for small 
values of x. A simple model
for a hidden-color, six-quark configurations (with~ 0.15% probability to 
exist in the deuteron)
is proposed and found to give substantial contributions for values of 
x>0.2. Good agreement with
Hermes data is obtained. Predictions are made for an upcoming JLab 
experiment. The Close & Kumano
sum rule is investigated and found to be a useful guide to understanding 
various possible effects
that may contribute.
