Optical Absorptions in Metal Sodium: The Temperature Dependence in the Liquid State

نویسنده

  • N. C. Haider
چکیده

The temperature dependence of optical absorptions in liquid Na is calculated. The electron energy values are obtained to second order in perturbation theory which are then used to determine the electron density of states. The density of states plots show some structure similar to those noted in the solid state. The optical conductivity in the liquid state is found to increase with the tem­ perature as in the solid state. The present calculation for the optical conductivity gives a rather sharp peak around hco = 1.7 eV. These results are in better agreement with the existing experi­ mental results.

Measurement and comparison of the temperature-dependence of refractive index of water and Plexiglas phantoms by interferometry method for their use in optical calorimetry

In radiation calorimetry by using laser beams and interferometry setups, variations induced by dose absorption in phantom can be precisely measured. Dose absorption and the induced temperature change result in refractive index variation of the material. In order to be able to measure the low amount of absorbed dose in the phantom, temperature dependence of refractive index of the material must ...
