Abstract

Inelastic neutron scattering scattering is employed to study transverse spin correlations of a Heisenberg S = 1/2 chain compound in a magnetic field of 7.5 T. The target compound is the well one-dimensional antiferromagnetic S = 1/2 Heisenberg chain material 2(1,4-Dioxane).2(H2O).CuCl2, or CuDCl for short. The validity and the limitations of the scaling relation for the transverse dynamic structure factor are tested, discussed and compared to the Tomonaga-Luttinger spin liquid theory and the Bethe-ansatz results for the Heisenberg model.
