Inelastic neutron scattering is used to study the finite-temperature scaling behavior of the local dynamic structure factor in the quasi-one-dimensional quantum antiferromagnet NTENP (Ni(N,N’-bis(3-aminopropyl)propane-1,3-diamine)(μ-NO2)ClO4), at its field-induced Ising quantum critical point. The validity and the limitations of the theoretically predicted scaling relations are tested.
