Nature of potential families from elastic 16O + 16O rainbow scatteringDedicated to the loving memories of F Bary Malik for inspiring us to use NM potentials; and Devika Basak, who was not only the loving wife of our group leader (AKB), but a source of extraordinary care, affection and inspiration for all his students and colleagues, sadly leaving us on 18 November 2020, just weeks before this article was accepted.

The experimental differential cross-sections of 16O + 16O elastic scattering in the energy range 75MeV ⩽ E lab ⩽ 1120 MeV are analysed using families of non-monotonic (NM) shallow nucleus–nucleus potential in the framework of the optical model. The experimental data is reproduced successfully using six families of NM potentials. It is found that all families converge at 350MeV. The clear indication of the convergence of the potential families at 350MeV conforms to the Goldberg criterion concerning the removal of discrete ambiguities even for the shallow NM potential. The study further suggests that the energy of convergence heralds the occurrence of the primary rainbow at that incident energy.

来自弹性 16O + 16O 彩虹散射的潜在家族的性质献给 F Bary Malik 的爱的回忆,激励我们使用 NM 电位;和 Devika Basak,她不仅是我们组长 (AKB) 的慈爱妻子,还是他所有学生和同事的非凡关怀、关爱和灵感之源,遗憾地于 2020 年 11 月 18 日离开我们,就在本文发表前几周公认。

使用光学模型框架中的非单调 (NM) 浅核 - 核势族分析能量范围 75MeV ⩽ E lab ⩽ 1120 MeV内16 O + 16 O 弹性散射的实验微分截面。使用六个 NM 电位族成功复制了实验数据。发现所有族均收敛于350MeV。潜在族在 350MeV 处收敛的明确指示符合戈德堡准则,即即使对于浅 NM 势也能消除离散模糊。该研究进一步表明,会聚能量预示着该入射能量下主彩虹的出现。
