The study show that the error in neglecting s-dependence affects strongly both the values of Uex and Utot . This effect is about 30 %( 23%) in Uex (Utot) for the force BDM3Y2 -Reid type while it is less than 7% for BDM3Y1-Ried. It decreases as α– α separation distance increases. For BDM3Y3 type force the corresponding error is too large at separation distance R=0.
