Abstract：
The chiral quark-soliton model with one gluon exchange is described simply in the present work,and the quark-gluon coupling constant and quark wave function,which are determined in this soliton model,are used to study two-nucleon system in the relativistic two-quark-cluster theory.Here kinetic energy and relative-motion energy terms are wholly considered in the quark-exchange kernel,therefore the phase shifts of ³S₁- and ¹S₀- shannels are improved.Our phase shifts are in agreement with those obtained by Arndt et al.It is shown that the one-gluon-exchange and quarkexchange mechanism offers a short-range repulsive potential while the chiral field produces a middle and long range attractive potential.
