Figure 17
(a) Decay time τ and (b) resolution as a function of neutron wavelength on IMAT. The experimental data shown in both panels were digitized from Ramadhan et al. (2019

) and they are fitted simultaneously using equations (8)

and (9)

. The parameters β₀ and β₁ determined from nonlinear least-squares fitting are listed. See text for further discussion.
