Imaging: Phase radiography with neutrons

The interaction of neutrons with matter enables neutron radiography to complement X-ray radiography in analysing materials. Here we describe a simple quantitative method that provides a new contrast mechanism for neutron radiography and allows samples to be imaged at low radiation doses. Large phase shifts can be measured accurately from detailed structures not amenable to conventional techniques.

Precision neutron interferometric measurements and updated evaluations of the n p and n d coherent neutron scattering lengths

We have performed high-precision measurements of the coherent neutron scattering lengths of gas phase molecular hydrogen and deuterium using neutron interferometry. After correcting for molecular binding and multiple scattering from the molecule, we find
