Generally, we study the inner frame of nucleus by means of scattering. The interactionbetween scattering particles is very complicated. According to the shell model, the nucleus mayregard as the shell structure of nucleon. While, based on the particlestructure model,αthenucleus is composed ofαparticle.In terms of the viewpoint ofαparticle,16O and 12C nucleus are typicalαparticlestructure, and it has been successfully tested.Based on the viewpoint ofαparticle,we applyαparticlefolding model optical potential to study the 16O+12C scattering under 100MeV,115.9MeV,124MeV,132MeV,170MeV,200MeV,230MeV and 260MeV energy in paper.When studying the 16O+12C scattering in the experiment angle less than 50 degree, firstly,we find better fitting by"watching value", and then, we obtain the best fitting for experimentdatum by the least square fitting. The results of the watching value and the least square fittingshow thatαparticle folding model can preferably reflect the 16O+12C scattering under theabove eight energies for the experiment angles less than 50 degree.In entire experimental angular distribution of the 16O+12C scattering, we firstly apply theoptical potential, which includes corresponding Coulomb potential, to describe the interactionbetween 16O and 12C nuclei:The results show that there are slight deviation between the outcome of calculating andexperiment data through(Ⅰ)formula at largeanglescattering range. In order to cut down ondeviation, the effect of theαparticlefolding model optical potential imaginary part on largeangle16O+12C scattering is studied. In paper, we apply the following two formats as the opticalpotential imaginary part:The simulation results show that applying(Ⅱ),(Ⅲ)formulas as theαparticlefolding model...
