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.

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，这一现象已被证明是表面科学中的一种强大的分析工具，具有许多非常吸引人的特征，如对最顶层的表面层非常敏感，对绝缘体靶材没有电荷效应，或表面结构的辐射损伤可以忽略不计。在这项建议中，应详细说明重要的特点，并打算测试紧凑型仪器的原型，目的是向更广泛的表面科学用户群体提供这项新技术。
