Fast Atom Diffraction during scattering from surfaces

该项目研究了在轴向表面散射的情况下，快光原子从表面的量子散射。近年来，这种现象已被证明具有作为表面科学中强大分析工具的潜力，具有许多非常吸引人的特征，如对最表层的极端敏感性，对绝缘体目标没有充电效应，或表面结构的可忽略不计的辐射损伤。在这项建议中，应详细阐明重要特征，并打算测试一种紧凑型仪器的原型，目的是使这种新技术可供表面科学领域更广泛的用户使用。

The project deals with the quantum scattering of fast light atoms from surfaces in the regime of axial surface scattering. This phenomenon has proven in recent years to have the potential as powerful analytical tool in surface science with a number of very attractive features as extreme sensitivity to the topmost surface layer, no charging effects for insulator targets, or negligible radiation damage of the surface structure. In this proposal important features should be cleared up in detail and a protype of a compact instrument is intended to be tested with the aim of making this new technique available for a broader community of users in surface science.
