Incoherent Neutron Spin-Echo Spectroscopy as an Option to Study Long-Range Lipid Diffusion

Figure 9

Quasielastic energy broadening (FWHM) as function of 𝑞²_||. The yellow data and fit were obtained from an experiment performed on the same system using neutron backscattering [8]. The diamond corresponds to the energy broadening which relates to the tau value from the single exponential used to fit 𝐼(𝑄,𝑡) in Figure 8(a). The two stars correspond to the tau values obtained from the double exponential fit shown in Figure 8(b).
