Proton dynamics in bacterial spores, a neutron scattering investigation

Proton dynamics in bacterial spores, a neutron scattering investigation

Results from first neutron scattering experiments on bacterial spores are reported. The elastic intensities and mean square displacements have a non-linear behaviour as function of temperature, which is in agreement with a model presenting more pronounced variations at around 330 K (57 ∘C) and 400 ...
