We address the question how a correspondence between particle-like exc
itations in the one-dimensional Hubbard model (i.e. ''holons'' and ''s
pinons'') and the free fermionic picture can be established in the lim
it of vanishing interaction by studying the finite size spectrum in th
e framework of the Bethe ansatz. Special attention has to be paid to t
he case of a vanishing magnetic field where the two bands of excitatio
ns in either description are degenerate. The interaction lifts this de
generacy.
