Description:
The phonon density of states of the geophysically important mineral forsterite has been calculated with a rigid-ion model, which gives good agreement with an experimental measurement by inelastic neutron scattering. The density of states has been used to calculate the specific heat as a function of temperature, the results of which are in excellent agreement with calorimetrically measured values. The rigid-ion model takes account of the interatomic interactions and normal modes of vibration on a detailed microscopic basis, and is therefore more realistic than the Debye and other empirical models used previously.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rao, K R -- Chaplot, S L -- Choudhury, N -- Ghose, S -- Price, D L -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):64-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17759206" target="_blank"〉PubMed〈/a〉
