Angular distributions of protons scattered by $$^{40}$$Ar nuclei with excitation of the 2$$^{+}$$ (1.46 MeV) and 3$$^{-}$$ (3.68 MeV) collective levels for incident energies of 25.1, 32.5, and 40.7 MeV

20から50MeVのエネルギー範囲における$$^{40}$$Arの陽子非弾性散乱の角度分布を2$$^{+}$$(1.46MeV)及び3$$^{-}$$(3.68MeV)準位に対して導出した。その結果をポテンシャルに分散項を含む軟回転体チャンネル結合模型を用いて解析し、核構造パラメータと光学ポテンシャルパラメータを導出した。

Elastic and inelastic scattering of unpolarized and polarized protons by $$^{40}$$Ar nuclei for incident energies between 20 and 50 MeV has been studied by reanalyzing experimental scattering spectra for the 2$$^{+}$$ (1.46 MeV) and 3$$^{-}$$ (3.68 MeV) levels in the angular range 30$$^{circ}$$ - 160$$^{circ}$$ for incident protons of energies of 25.1, 32.5, and 40.7 MeV. An isospin dependent soft-rotator coupled channels optical model with the potential containing a dispersive term with a nonlocal contribution is used to analyze the data.
