a Constant momentum cuts at points along the [\(H\), 0, 0.5]Ā direction measured using HYSPEC at SNS, integrated over \(H\)ā=ā[\(H\)ā0.05, \(H\)+0.05] at selected \(H\), \(K\)ā=ā[ā0.1, 0.1], and \(L\)ā=ā[0.4, 0.6]. b Constant momentum cuts at points along the [\(H\), \(H\), 0.5]Ā direction measured using CTAX at HFIR. Blue bars at the bottom of the panels indicate the instrumental resolutions for HYSPEC and CTAX at the proximate energy transfers. The blue and orange shaded regions are the results of fitting Gaussian line shape to transverse (\({T}_{1}\), \({T}_{2}\)) and longitudinal (\(L\)) modes, respectively.
