    Abstract

    Electron energy loss spectroscopy of MgH 2 in the plasmon energy range is reported here as a part of a study to determine the dielectric function of this hydride. From the dielectric function, we have estimated the unperturbed plasmon energy of MgH 2 as 11.34 eV. Interband transitions are also inferred from the dielectric function. Contribution of these interband transitions to the perturbed plasmon energy has been discussed within the scope of dielectric theory. Our analysis suggests that the MgH 2 band gap lies within the range ∼4.3-4.5 eV.
