Abstract
The similarity in the masses of the proton and the neutron, and the extremely large scattering cross-section for hydrogen make neutron an ideal probe for studying the dynamics of hydrogen in materials. With neutron scattering it is possible to measure the excitation energies of hydrogen as well as the intensity maps I (Q, ε) at those excitations in a wide Q-range. The measurements of the intensity map I (Q, ε) directly probe the shape of the hydrogen wave function, and can give us the further novel information for the exact hydrogen potential.This new method was applied to determined the hydrogen potential in the hydrogen bond for the first time.
