论文摘要
我们使用簇核的簇有效的场理论研究了单中无晕核核的弱衰变,即从光环核中脱离β降低的质子发射的弱衰变。一方面,我们将直接衰减计算为连续体。另一方面,我们考虑了质子与核心之间的共振最终状态相互作用的情况。我们介绍形式主义,并讨论$^{11} $的衰减的应用。此外,我们将分支比和共振参数的最新实验结果进行比较。作为另一个例子,我们考虑了$^{19} $ c的情况,并预测了β延迟的质子发射的分支比率。
We investigate the weak decay of one-neutron halo nuclei into the proton-core continuum, i.e., beta-delayed proton emission from the halo nucleus using a cluster effective field theory for halo nuclei. On the one hand, we calculate the direct decay into the continuum. On the other hand, we consider the case of resonant final state interactions between the proton and the core. We present our formalism and discuss the application to the decay of $^{11}$Be in detail. Moreover, we compare to recent experimental results for the branching ratio and resonance parameters. As another example, we consider the case of $^{19}$C and predict the branching ratio for beta-delayed proton emission.
