用双中子动力学模型探讨双中子辐射中双中子的表现和性质
Exploring manifestation and nature of a dineutron in two-neutron emission using a dynamical dineutron model
摘要：
在反应和衰变中发射两个中子或两个质子经常被称为“双中子”或“双质子”发射。这种讨论往往直观地依赖于Migdal-Watson近似所描述的东西。在这项工作中，我们提出了一种方法来正式的双中子发射的情况。它表明，适当的正式定义的双中子发射可能会揭示的属性是彻底不同于传统的预期，并实际观察到的三体衰变的属性。
英文摘要：
Emission of two neutrons or two protons in reactions and decays is often discussed in terms of "dineutron" or "diproton" emission. The discussion often leans intuitively on something described by Migdal-Watson approximation. In this work we propose a way to formalize situations of dineutron emission. It is demonstrated that properly formally defined dineutron emission may reveal properties which are drastically different from those traditionally expected, and properties which are actually observed in three-body decays.
