英文摘要：

Based on the a-particle model of ^12C nuclear,the 2^＋ and 3^- excited states transition density is presented by fitting the experimental transition form factor data of electron scattering. In the framework of KMT theory,the differential cross sections of 600 MeV and 700 MeV p-^12C inelastic scattering for 2^＋ and 3^- excited states have been calculated by using the obtained transition density. The theoretical resuits are in agreement with the experimental data. The results provide support for the α-particle excitation mechanism for the 2^＋ and 3^- states of ^12C nuclear in the field of p-^12C inelastic scattering.
