Title

Using polarization analysis to separate the coherent and incoherent scattering from protonated and deuterated protein samples

Abstract

We want to use polarization analysis to separate experimentally the coherent and spin-incoherent nuclear static scattering functions, from a set of protonated and deuterated samples of green fluorescent protein. We studied the same two samples by elastic and inelastic neutron scattering on IN5 as function of temperature to validate a recent formalism proposed by G. Kneller in the aim to determine whether quantum effects can be probed by neutron scattering. Data analysis gave already encouraging results, but we need to be sure about the contributions from coherent and incoherent scattering to separate the all effects. For that, polarisation analysis is ideal and can be employed on IN12.
