10から50MeV領域におけるLiによる重陽子弾性散乱を、離散化連続チャンネル結合法(CDCC)により解析した。CDCC計算に必要な核子と原子核間の光学ポテンシャルは現象論的な光学模型解析により導出した。これにより核子・原子核と重陽子・原子核反応を整合的に記述できるポテンシャルを構築することができた。

The continuum discretized coupled channels (CDCC) approach is applied to analysis of deuteron elastic scattering from Li in the energy range from 10 to 50 MeV. Phenomenological neutron and proton optical potentials which are essentially important in the CDCC calculation are determined from the present optical model analysis of differential cross sections of nucleon elastic scattering, neutron total cross sections, and reaction cross sections of Li for energies from 5 to 50 MeV. The CDCC result provides satisfactory agreement with experimental data, particularly at forward angles. The obtained nucleon optical model potentials are found to describe reasonably well both nucleon and deuteron elastic scattering from Li for energies up to 50 MeV.
