Abstract

The thick target inverse kinematics (TTIK) approach was used to measure excitation functions for the elastic \({}^{17}\)O (\(\alpha,\alpha\)) scattering at the initial \({}^{17}\)O beam energy of 54.4 MeV. We observed strong peaks corresponding to highly excited \(\alpha\)-cluster states in the \({}^{21}\)Ne excitation energy region of 8–16 MeV, which have never been investigated before. Additional tests were done at a \({}^{17}\)O beam energy of 56.4 MeV to estimate a possible contribution of resonance inelastic scattering.

摘要

厚目标逆运动学（TTIK）方法用于测量初始\ {{} ^ {处的弹性\（{} ^ {17} \） O（\（\ alpha，\ alpha \））散射的激发函数17} \） O束能量为54.4 MeV。我们在8–16 MeV的\（{} ^ {21} \） Ne激发能量区域中观察到了与高激发\（\ alpha \）-簇状态相对应的强峰，这是以前从未研究过的。在\（{} ^ {17} \） O束能量为56.4 MeV的情况下进行了其他测试，以估计共振非弹性散射的可能贡献。
