We have calculated dispersion of optical constants ε2average(ω). We have established that application of different exchange correlation potentials XC has no significant effect on the optical constant dispersion. Moreover, use of LDA, GGA and EVGGA has an insignificant effect on the corresponding optical features. The crystallochemical transformation between the two titled compounds leads to a spectral shift of the whole ε2average(ω) structure: for ZrGa 3 it leads to higher energy shift with respect to ZrGa2. Moreover, one can see that the first spectral peak of ε2average(ω) for ZrGa2 which situated at around 0.5 eV becomes very small for ZrGa3 but still situated in the same location. The first right hand side hump in ε2average(ω) - ZrGa2 which is located at around 1.5 eV becomes pronounced and situated at around 2.2 eV in ε2average(ω) - ZrGa3. For more complete information we have calculated dispersions of the electronic loss function, reflectivity and the optical conductivity. 2014-01-14T13:40:35Z 2014-01-14T13:40:35Z 2012-01 Article Journal of Alloys and Compounds, vol. 546, 2012, pages 14-19 0925-8388 http://www.sciencedirect.com/science/article/pii/S0925838812014752 http://dspace.unimap.edu.my:80/dspace/handle/123456789/31194 en Elsevier B.V.
