37. Some other functional forms for a damped harmonic oscillator such as the one described in H. R. Glyde, Excitations in Solid and Liquid Helium (Clarendon Press, Oxford, 1994), pp. 184–185 are of use in the case when the inelastic intensity arises from single-mode excitations. In our case, where the measured intensity has to be ascribed to excitations of rather different characters, we made use of this simpler formula.
