Abstract
Based on symmetry consideration, more generalized chiral field terms a re proposed to restore the chiral SU(2)(L)xSU(2)(R) symmetry of strong interaction. As a result, a modified quark-quark interaction is obtai ned. Applying this interaction to nucleon-nucleon scattering, the agre ement between the theoretical phase shifts of partial waves and experi mental data is improved.
