The adsorption of molecular hydrogen (H2) in the alkali-graphite intercalate KC24 has been studied using simultaneous neutron diffraction and Compton scattering. Neutron Compton scattering data for the (H2)xKC24 system (x = 0-2.5) were measured at T = 1.

- The study focuses on how molecular hydrogen (H2) is absorbed in the graphite intercalation compound KC24, using both experimental methods and theoretical models.
- High-resolution inelastic neutron data reveal that H2 strongly aligns along a specific axis within the compound, while advanced calculations provide new insights into how H2 binds but don't fully match experimental observations.
- The discrepancy is resolved by allowing H2 to spread across multiple adsorption sites, which leads to the expected saturation of about 2H2 per metal atom, highlighting the significant role of quantum mechanics in hydrogen storage in carbon materials.
