Details of the neutron TOF pattern of cubic Ca3Al2Na2F14 (`NAC', space group I213, a = 5.46 Å; minor phase CaF2 also present) from POWGEN (SNS, Oak Ridge National Laboratory) for the 1.0 < λ < 2.0 Å band (2 = 90°,
L* = 63.18 m) plotted as Q = 2π/d = 252.816
L* sin /π
T*. (a) A diffraction peak at low Q (d = 5.126 Å,
T* = 115 570 µs) and (b) 14 diffraction peaks at high Q (d ≃ 0.5 Å, 12 100 <
T* < 12 600 µs). The `+' marks are the observed data points and the curves are guides to the eye connecting them. |
