论文摘要
通过衍射光栅的原子的波函数获得了规则的空间结构，并且另一个粒子与该原子的相互作用可以被认为是由单个原子组成的“量子光栅”上的散射。通过与带电弹丸的碰撞探测这种“光栅”，揭示了由于其“缝隙”对过渡幅度的“缝隙”的连贯贡献引起的干扰效应。特别是，与Swift离子碰撞中原子发出的电子光谱表现出明显的干扰模式，其形状可能对碰撞速度极为敏感。
The wave function of an atom passed through a diffraction grating acquires a regular space structure and the interaction of another particle with this atom can be thought of as scattering on a 'quantum grating' composed of a single atom. Probing this 'grating' by collisions with charged projectiles reveals interference effects due to coherent contributions of its 'slits' to the transition amplitude. In particular, the spectra of electrons emitted from the atom in collisions with swift ions exhibit a pronounced interference pattern whose shape can be extremely sensitive to the collision velocity.
