State density of phonons in cadmium
Eremeev I.P. , Chernyshov A.A. , Sadikov I.P.
Using inelastic neutron scattering, we determined the density g(to) of the phonon states in cadmium. The measurements were performed on a mixture of the isotopes Cd-110 and Cd-111. The density of states was obtained by integrating the cross section for scattering by a polycrystal in a wide range of momentum transfers. Using the analogy between g(to) of Cd and Zn, we determined the frequencies of the phonons in cadmium for certain symmetric points of the Bril-louin zone.
