Description

A new mechanism of neutron acceleration in the accelerated perfect crystal is proposed and found experimentally. The effect arises due to the resonance energy dependence of neutron refraction index in a perfect crystal for neutron energies, close to the Bragg ones. As a result during the neutron time-of-flight through the crystal the value of deviation from the exact Bragg condition changes and so the refraction index and the velocity of outgoing neutron changes as well.
