The foundations of our work lie in physics, where we study processes involving the innermost electrons that orbit the atom. One such process is the ejection of these electrons by swift heavy projectiles such as protons from a particle accelerator, and another is the emission of characteristic X-rays during the subsequent relaxation of the excited atom. Our experiments are interpreted through highly refined computer analysis of the energy distributions of these X-rays.

我们工作的基础在于物理学，在那里我们研究涉及原子轨道最内层电子的过程。一个这样的过程是这些电子被快速的重射弹（如来自粒子加速器的质子）射出，另一个是在激发原子随后的弛豫期间发射特征X射线。我们的实验通过对这些X射线的能量分布进行高度精确的计算机分析来解释。
