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 Å, 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. © 2015 Wiley Periodicals, Inc.
