By deriving and studying the coordinate representation for the one-spinonone-holon wavefunction we show that spinons and holons in the supersymmetric $t- J$ model with $1/r^2$ interaction attract each other. The interaction causesa probability enhancement in the one-spinon one-holon wavefunction at shortseparation between the particles. We express the hole spectral function for afinite lattice in terms of the probability enhancement, given by the one-spinonone-holon wavefunction at zero separation. In the thermodynamic limit, thespinon-holon attraction turns into the square-root divergence in the holespectral function.Comment: 20 pages, 3 .eps figure
