Název v původním jazyce

Sensitivity of electron and electron-positron momentum densities to various electron and positron crystal potentials.

Popis výsledku v původním jazyce

This paper presents a comprehensive survey on the influence of various crystal potentials used for the calculation of electron and positron Bloch states on electron and electron-positron momentum densities. Our investigation deals with alkali metals andthe complete series of 4sp and 3d metals, and it covers both the behavior of valence and core electrons as well as the central momentum region and some Umklapp regions. The main results of this paper are: (i) the sensitivity of the electron-positron momentum density with respect to various crystal potentials is significantly higher for 4sp and 3d metals than for the alkali metals, (ii) for all metals of the 3d series, the electron-positron momentum densities are generally more sensitive to the potentials than the corresponding electron momentum densities. Possible complications regarding the comparison of theoretical and experimental electron-positron momentum profiles and extracting information on electron-positron interaction are also
