Abstract

The total scattering cross sections for slow neutrons with energies E in the range 300 neV to 3 meV for gaseous and liquid ortho-H22 have been measured. The cross sections for H22 gas are found to be in excellent agreement with both the Hamermesh and Schwinger and the Young and Koppel models. For liquid H22, we confirm the existing experimental data in the cold neutron range and the discrepancy with the gas models. We find a clear 1/E′ dependence at low energies for both states. A simple explanation for the liquid H22 cross section is offered.
