New experimental neutron scattering data from fluid and solid molecular hydrogenat high momentum transfer are interpreted by means of a theoretical calculation able to describethe data both for parahydrogen and for an ortho-parahydrogen mixture over a wide momentumtransfer range. Our approach, valid for any diatomic molecule, reveals the occurrence of finalstate effects in the scaling function and their q dependence. It appears that at high momentumtransfer the dominant final state effects are those coming from the intramolecular interaction

Abstract
New experimental neutron scattering data from fluid and solid molecular hydrogenat high momentum transfer are interpreted by means of a theoretical calculation able to describethe data both for parahydrogen and for an ortho-parahydrogen mixture over a wide momentumtransfer range. Our approach, valid for any diatomic molecule, reveals the occurrence of finalstate effects in the scaling function and their q dependence. It appears that at high momentumtransfer the dominant final state effects are those coming from the intramolecular interactionFile in questo prodotto:
