By performing time-of-flight neutron scattering measurements on a large sample of single crystals of Sr${}_{2}$RuO${}_{4}$, we studied the detailed structure of the imaginary part of the dynamic spin susceptibility over a wide range of phase space. In the normal state at $T=5$ K, strong incommensurate (IC) peaks were clearly observed …
