In this work we will present an overview of our global studies on continuum excitations induced by protons, for the weakly bound nuclei \(^6\hbox {Li}\), \(^7\hbox {Li}\) and \(^9\hbox {Be}\), presenting strong clustering modes. Measurements are made in inverse kinematics and extensive simulations have been developed, to corroborate the analysis and interpretation of the results. The focus of the measurements is on the breakup reaction, but simultaneously this research is complemented by the study of all involved reaction channels, including elastic scattering. In this respect our theoretical interpretation in a Continuum Discretized Coupled Channel approach can be fully validated. Between our sound conclusions we can underline the following: the non reciprocity between the strengths of the breakup probability and the coupling to continuum; the experimental validation of a continuum discretization for three body Continuum Discretized Coupled Channel theories; and last but not least the unique possibility for deducing continuum decay rates of borromean nuclei in proton induced studies, by considering the kinematics of the target recoil. Other specific conclusions for each system will be discussed.

弱束缚核连续激发的整体描述和衰减速率

在这项工作中,我们将概述关于质子弱束缚核\(^ 6 \ hbox {Li} \)\(^ 7 \ hbox {Li} \)\( ^ 9 \ hbox {是} \),呈现出强大的聚类模式。在逆向运动学中进行了测量,并且已经开发了广泛的模拟,以证实对结果的分析和解释。测量的重点是分解反应,但同时,这项研究得到对所有涉及的反应通道(包括弹性散射)的研究的补充。在这方面,我们对连续离散离散耦合通道方法的理论解释可以得到充分验证。在我们得出的合理结论之间,我们可以强调以下几点:分手概率与耦合到连续体之间的不互惠性;三体连续体离散耦合通道理论的连续体离散化的实验验证;最后但并非最不重要的一点是,通过考虑目标反冲的运动学,在质子诱导的研究中推导硼烷核的连续衰变速率的独特可能性。将讨论每个系统的其他特定结论。
