摘要
在阿斯塔纳回旋加速器上，使用TTIK方法研究了6.5到9 MeV的\(^{18}\)F激发区域的共振\(^{14}\)N+(\alpha \)粒子散射。在 R 矩阵计算框架内分析了弹性 \(^{14}\)N+\(α \)散射的激发函数。观察到的\(^{18}\)F中的强α簇结构与\(^{18}\)O中的强α簇结构进行了比较。虽然两个原子核的结构基本一致，但在 l = 4 共振中发现了惊人的差异。实验结果与构型相互作用计算结果进行了比较。
\(^{18}\)F alpha cluster structure in the resonant \(^{14}\)N+\(\alpha \) scattering
The resonant \(^{14}\)N+\(\alpha \) particle scattering was studied in the \(^{18}\)F excitation region from 6.5 to 9 MeV at Astana cyclotron using the TTIK approach. The excitation functions for the elastic \(^{14}\)N+\(\alpha \) scattering were analyzed in the framework of R matrix calculations. The observed strong alpha cluster structure in \(^{18}\)F is compared with that in \(^{18}\)O. While the general agreement of the structure in both nuclei is confirmed, a striking difference for l = 4 resonances is found. The experimental results are compared with configuration interaction calculations.
