论文摘要
我们提出了一个半微观模型，用于同时发射两个质子。该模型的优点是避免了完全微观3体框架的某些技术方面，同时还可以研究质子配对对衰减核的总寿命的影响。因此，我们在核表面上使用标准的单重螺旋体波函数，由Bardeen-Cooper-Schrieffer（BCS）方法提供，作为传播器操作员的边界条件。 我们的模型允许估计与$ 2P $排放过程相关的所有数量，因为它在大多数域上提供了3体波函数。我们表明，可以通过在接近“裸机”单元值的间隔以外的间隔以外的$ pp $配对强度来改变与实验值的合理一致。
We propose a semi-microscopic model for the simultaneous emission of two protons. This model has the advantage of avoiding certain technical aspects of a fully microscopic 3-body framework, while also allowing the investigation of the influence of proton pairing on the total lifetime of the decaying nucleus. Thus, we use the standard singlet two-proton wave function on the nuclear surface, provided by the Bardeen-Cooper-Schrieffer (BCS) approach, as a boundary condition for the propagator operator. Our model allows for the estimation of all quantities related to the $2p$ emission process, since it provides the 3-body wave function over most of the domain. We show that reasonable agreement with experimental values can be reached by varying the $pp$ pairing strength outside the nucleus in an interval close to the "bare" singlet value.
