Electromagnetic Studies of Few-Body Nuclear Physics

* 9733791 Templon原子核由核子（中子和质子）组成;它们通过强的短程排斥力和长程但较弱的吸引力的微妙平衡结合在一起，这些吸引力在核子对之间起作用。 吸引力在许多已被充分研究的核现象中表现出来，但短程排斥力被证明是难以捉摸的，只能在核中间接地进行研究。在该资助下进行的研究旨在研究由电子束轰击引发的核反应，该反应对核子之间的短程排斥力非常敏感。 这些核反应进行的机制也将被研究，因为这些反应发生的概率很小，因此对其他可能发生的多步反应很敏感。 其中一些多步反应本身就很有趣，因为它们依赖于核子的夸克结构，而夸克是中子、质子、介子和原子核的最终基本粒子。

***9733791TemplonThe atomic nuclei consists of nucleons (neutrons and protons); these are bound together by a delicate balance of strong, short-range repulsive forces and longer-range but weaker attractive forces, which operate between pairs of nucleons. The attractive forces are exhibited in many well-studied nuclear phenomena, but the repulsive short-range forces have proved elusive and have only been studied indirectly in nuclei.The research carried out under this grant is aimed at studying nuclear reactions, initiated by electron-beam bombardment, which are explicitly sensitive to the short-range repulsiveforces between the nucleons. The mechanism by which these nuclear reactions proceed will also be studied, since these reactions occur with very small probability and are therefore sensitiveto other, multiple-step reactions which can occur. Some of these multiple-step reactions are interesting in their own right anyway, since they depend on the quark structure of nucleons, and quarksare the ultimate fundamental particles from which neutrons, protons, mesons and nuclei are made.***
