摘要

Quantum entanglement (QE) in micro- and mesoscopic systems in condensed matter is very short-lived due to interactions with the environment. However, neutron Compton scattering (NCS) operates in the attosecond time scale, thus allowing to access QE effects of protons with electrons. Our findings revealed a striking shortfall of NCS-intensity from protons of M-H and various molecular systems; in simple terms, about 20-4-0 percent of the protons seem to "disappear". This new effect was recently confirmed with a completely independent method: electron Compton scattering from nuclei (ECS). During the scattering process there is no well-defined time-scale separation between protonic and electronic "motions" and thus the Born-Oppenheimer (BO) approximation is not applicable. A theoretical outline of the NCS (and ECS) results is presented. This theory also applies to other fast processes, like H-jumps, formation or breaking of a chemical bond, electron mobility and/or transfer, etc.
