The α+¹⁶O Cluster Structure Of ²⁰Ne By Interaction Potential、State Wave Function And P-²⁰ Ne Scattering

The intermediate-energy proton-nucleus scattering is one of the important meth-ods to study the inner structure of nucleus, based on the standpoint of cluster structure inα+16 O model of 20Ne nucleus, some different α+16 Ointeraction potential, and 0+、 2+and 4+ state wave functions 20Ne, and the corresponding ground state form fac-tor and 2+and 4+ excited state transition form factors have been done, with the use of electron scattering experiments which measured 20Ne nucleus ground state form factor,2+and 4+ transition form factors, as well as proton and elastic scattering and inelastic scattering experiments of 20Ne.B.Buck et al used W - S potential and N - N folding potential to get the energy spectra and the relative motion wave function in α+16 O model of 20Ne nucleus. The energy spectra can match the experimental results well, but the relative motion wave function in α+16 O model of 20Ne nucleus remains to be examined further.We check up the research on the relative motion wave function in α+16 O model of 20Ne nucleus obtained by B.Buck et al, with the use of electron scattering and elastic and inelastic in p-20 Ne.We solved the Schrodinger equation to get 0+、2+ and 4+state wave functions and energy spectra in 20Ne by using W - S potential and N - N folding potential, and calculated the ground state form factor,2+ and 4+ transition form factors by using 0+、2+ and 4+state wave functions. Compare the ground state form factor,2+ and 4+ transition form factors in the nuclear of 20Ne which are measured in electron scattering experiment with the calculated results, we can find that the ground state form factor matches well with the experimental value, while there are large deviations between the 2+ and 4+ transition form factor and experimental values.We applied 0+、2+ and 4+ state wave function in the framework of Glauber scattering theory to calculate elastic and inelastic scattering differential cross section in p -20 Ne when Tp=800MeV.Comparison between calculated results and the experimental values: calculated elastic scattering matches well with the experimental value, while there is a great deviation between inelastic scattering with experimental value.The comparison above shows that there are some problems for B.Buck et al to calculated wave functions by using W - S potential and N - N fold potential. Several different α+16O interaction potentials have been tried,namely:a folding potential and molecular potential,We solved the Schrodinger equation to get energy spectra and 0+、2+ and 4+state wave functions.and we check up the research by calculating electron scattering form factor and excited state form factor and elastic and inelastic in p-20 Ne, in order to get more reasonable description of the interaction potential and characteristics information of α+16O cluster structure in 20Ne nucleus.The results shows:Only the ground state form factor matches well with the experimental value, while there is a deviation between other excited state transition form factors and the experimental values; calculated elastic scattering in p -20 Ne matches well with the experimental value,while there is a deviation between calculated elastic scattering and the experimental value.Thus based on the results above, in this thesis, different α+16 Ointeraction potentials are used to solve the 0+、2+ and 4+ state wave function in 20Ne, the ground state form factor and elastic scattering differential cross section in p -20 Ne match well with the experimental values, but there are great deviations between the excited state transition form factors and inelastic scattering differential cross section in p -20 Ne and the experimental values, more reasonable α+16 O interaction potentials are needed for the further research.
