The effective baryon-baryon potential can be derived in the framework of quark model.
The configurations with different quark spatial distributions are mixed naturally when two baryons
are getting close. The effect of configuration mixing in chiral quark model (ChQM) is studied by
calculating the effective potential between two nonstrange baryons in the channels I J = 01, 10 and
03. For comparison the results of color screening model (CSM) are also presented. Generally the
configuration mixing will lower the potential when the separation between two baryons is small, and
its effect will be ignorable when the separation becomes large. Due to the screened color confinement,
the configuration mixing is rather large, which leads to stronger intermediate-range attraction in
CSM. while the effect of configuration mixing is small in ChQM due to the quadratic
