Popis:	The experimental data of 12C(p,p?)(p,n) in the low-energy region (80 MeV) were analysed using M3Y effective interaction and Halderson's effective interaction in the theoretical frame of distorted wave Born approximation. By comparing the calculation results of the two effective interactions, it was observed that the isovector spin-dependent central part V and the isovector tensor-exchange part VT E of Halderson's effective interaction are appropriate for describing the experimental data. This analysis also suggests that the isoscalar tensor-exchange part VTOE of Halderson's effective interaction should be substantially reduced to obtain agreement with the experimental ratio of cross sections 12C(p,p?) 12C [d/d(1+,T = 0)]/[d/d(1+,T = 1)] at zero degree, and this reduction did not change the good agreement with experimental data for excitation of the (1+,T = 1) state.
