Fitting results from TOF-QENS data. (A) Neutron energy transfers, FWHM, versus Q2 fit with a jump diffusion model (Eq. 4) for Np, Ip, and Rp at 50 mg/ml. Inset shows FWHM versus Q without fitting. (B) EISF for Np, Ip, and Rp at 50 mg/ml (solid points), and for Np and NpP at 100 mg/ml (open points). Lines indicate fits according to Eq. 9. Error bars indicate fitting errors. Error bars that are not visible are smaller than the data point symbols.
