DFT calculations of the electron – positron energy correlation in metal Cu (FCC)

Abstract

In this article, density functional theory (DFT) and quantum Monte – Carlo method are applied for caculating the electron – positron energy correlation in copper metal with FCC structure. The caculations pointed out that this value was about -10,28 ± 1,11 eV. This value is similar to Puska [5] and Nieminen’s the results [6].
