The project aims at the investigation of a novel phenomenon in quantum mechanics, i. e. short-lived (appearing in the range of 100-1000 attoseconds) quantum entanglement. The possibility to measure this phenomenon emerged with the onset of a new technique, i. e. neutron Compton scattering, thanks to its ultra short scattering times. The technique is implemented at the unique time of flight spectrometer VESUVIO, ISIS facility, the Rutherford Appleton Laboratory, UK. Measurements on VESUVIO have demonstrated a striking effect – an “anomalous” shortfall of the total scattering cross section from protons in a variety of materials. The intention is to extend the scope of my research, conducted so far at the Technical University of Berlin (TUB), through a two-year research period at ISIS, with long-term objective being "Habilitation" at the TUB. The project will be supervised by Dr. Jerry Mayers of ISIS whose experience in the field will play crucial role its realization. It will have two major objectives; (1) development of new methods of data treatment and experiment modelling in Neutron Compton scattering with particular emphasis on the implementation of a new experimental technique - a constant momentum transfer measurement (2) the investigation of the role of electronic environment and momentum distribution of the struck particles in “anomalous” shortfall of total scattering cross section. A series of measurements will be performed and a theoretical analysis will be attempted on a family of compounds where the electronic structure changes in a systematic way.

该项目旨在研究量子力学中的一种新现象，即。e.短暂的（出现在100-1000阿秒的范围内）量子纠缠。测量这种现象的可能性随着一种新技术的出现而出现，e.中子康普顿散射，由于其超短的散射时间。该技术在英国卢瑟福阿普尔顿实验室ISIS设施独特的飞行时间光谱仪VESUVIO上实施。VESUVIO上的测量已经证明了一个惊人的效果-质子在各种材料中的总散射截面的“异常”不足。目的是扩大我的研究范围，到目前为止，在柏林技术大学（TUB）进行的研究，通过在ISIS为期两年的研究期，长期目标是在TUB的“障碍”。该项目将由伊斯兰国的Jerry Mayer博士监督，他在该领域的经验将对其实现发挥关键作用。它将有两个主要目标：（1）在中子康普顿散射中开发新的数据处理和实验建模方法，特别强调实施新的实验技术-恒定动量传递测量（2）调查电子环境和撞击粒子的动量分布在总散射截面“异常”短缺中的作用。将进行一系列的测量，并尝试对电子结构以系统方式变化的化合物家族进行理论分析。
