11Be中子晕基态的β延迟质子发射由于其异常高的衰变速率而引起了人们的广泛关注。有人认为，这可能是由于在质子衰变阈值之上存在共振。在本文中，我们使用实能量连续体壳层模型的透镜来描述几个观测值，包括β -延迟α和质子衰变的伽莫-泰勒速率，并认为，在我们的模型中，大的β - p分支比不能与其他数据相协调。
Beta-delayed proton emission from the neutron halo ground state of 11Be raised much attention due to the unusually high decay rate. It was argued that this may be due to the existence of a resonance just above the proton decay threshold. In this Letter, we use the lenses of real-energy continuum shell model to describe several observables including the Gamow-Teller rates for the β−-delayed α and proton decays, and argue that, within our model, the large β−p branching ratio cannot be reconciled with other data.
