  The quark delocalization and color screening model is used for a systematic
study of the effective potential between baryons in the u,d and s sector. The
model is constrained by the properties of baryons and N-N scattering. The
effective potentials for the N-N (IJ=01,10,11,00) channels and the N-Lambda and
N-Sigma (IJ = (1/2)1, (1/2)0, (3/2)1, (3/2)0) channels fit the N-N, N-Lambda
and N-Sigma scattering data reasonably well. This model predicts: There are
rather strong effective attractions between decuplet-baryons; the effective
attractions between octet-baryons are weak or even repulsive; and the
attractions between decuplet- and octet-baryons lie in between.
