  We address the question how a correspondence between the particle like
excitations in the one dimensional Hubbard model (i.e. ``holons'' and
``spinons'') and the free fermionic picture can be established in the limit of
vanishing interaction by studying the finite size spectrum in the framework of
the Bethe Ansatz. Special attention has to be paid to the case of a vanishing
magnetic field where the two bands of excitations in either description are
degenerate. The interaction lifts this degeneracy.
