Eighty years after the establishment of quantum mechanics protons in matter are still largely seen as 'classical' particles, that do not interfere in ways known to occur for light and electrons. There are indications from neutron and electron scattering experiments from solids that, for extremely short time scales, (one-millionth of a nanosecond), this picture is too simple. The proposed experiment seeks to establish this fact for molecules in the gas-phase. As the chemical bond is formed at similar time-scales these experiments will improve our understanding of chemical reactions, and hence be of great value for the chemical industry.

在量子力学建立80年后，物质中的质子在很大程度上仍然被视为“经典”粒子，它们不会以已知的方式干扰光和电子。固体的中子和电子散射实验表明，对于极短的时间尺度（百万分之一纳秒），这幅图太简单了。所提出的实验试图为气相中的分子确立这一事实。由于化学键是在相似的时间尺度上形成的，这些实验将提高我们对化学反应的理解，因此对化学工业具有重要价值。
