  The elementary excitations of strongly correlated one-dimensional electronic
systems - spinons and holons - are discussed in an exact solution of the
Haldane-Shastry and Kuramoto-Yokoyama model. We derive and exactly solve the
equation of motion both for the two-spinon wavefunction and for the one-spinon,
one-holon wavefunction. By solving the equations of motion we find the
spinon-spinon and spinon-holon interaction to be a short-range attraction. The
physical consequences of such an attraction on the spin-form factor and on the
hole-spectral function are also worked out.
