Entanglement creation in Compton scattering of neutrons on protons and its possible energetic consequences

• It has been predicted that entanglement creation should be associated with a lowering of energy (as well as the well-known decrease of entropy) for certain types of interaction potentials. This is a principally important question and it is shown here that np-scattering has specific features that would make it suitable for experimental tests of this prediction using neutron scattering on hydrogen at high angles. For this purpose, the evolution of n-p entanglement in Compton scattering on protons at epithermal energies (20-200 eV) is calculated over the separation distance 0-1 angstrom, corresponding to times up to 10(-15) s after the collision. If an energy transfer is associated with the entanglement, it ought to be observable under these measurement conditions.
