Neutron spectroscopy results from LET (ISIS) are presented in Figure . Figures ) illustrate the background corrected data at T = 2 K using the detailed balance analysis to extract 𝑆𝑆�𝑄𝑄 �⃗ , 𝜔𝜔� for incident energies of Ei = 12 and 3 meV. In both panels, we have corrected for a phonon background using the extracted 𝑆𝑆�𝑄𝑄 �⃗ , 𝜔𝜔� at T = 80 K by,
