Sn. Behera et Ua. Salian, RAMAN-SCATTERING IN CUPRATE SUPERCONDUCTORS - RESULTS OF A FINITE WAVE VECTOR (Q) CALCULATION, Solid state communications, 91(5), 1994, pp. 351-356
An earlier first principle calculation of the Raman Intensity for the
cuprate superconductors is generalised to take into acount the finite
penetration depth of light in these materials. The intensities are cal
culated at finite but small q and at zero temperature. The results pro
vide qualitative explanation of the experimental data.
