论文摘要
$^{208} $ pb的最近得出的分散光学模型电位（DOMP）扩展了，以考虑在Fermi Energy附近的核假想电位定义的真实电势和壳间隙中的非本地性。修改后的DOMP改善了$^{208} $ pb和$^{208} $ pb粒子孔绑定状态的核子散射的同时描述。新电位显示出对近魔法目标的核子散射数据的很好描述$^{206,207} $ pb和$^{209} $ bi。
A recently derived dispersive optical model potential (DOMP) for $^{208}$Pb is extended to consider the non-locality in the real potential and the shell-gap in the definition of the nuclear imaginary potentials near the Fermi energy. The modified DOMP improves the simultaneous description of nucleon scattering on $^{208}$Pb and of the $^{208}$Pb particle-hole bound states. The new potential is shown to give a very good description of nucleon scattering data on near-magic targets $^{206,207}$Pb and $^{209}$Bi.
