Quark Delocalization, Color Screening and Intermediate Range Attraction of Nuclear Force

Key words: 
• delocalization /
• color screening /
• nuclear force

Abstract: We introduce the quark delocalization and color screening into the usual quark modeland the property of nuclear force. The resulting N-N phase shifts and the adiabatic potential aredescribed qualitatively well: there are exclusion core and also intermediate range attraction, but thereis no Van der Waals force. The delocalization parameter obtained from variational method is alsoreasonable. we consider especially the effect of mass center motion, the effect of forms of colorscreening...
