Positron work function and deformation potential

Electron and positron chemical potentials at a given crystal volume are obtained from first-principles density-functional calculations. The calculated chemical potentials are used to obtain the positron work function and deformation potential. The results are compared with previous calculations for...

Beschreibung
Zusammenfassung:	Electron and positron chemical potentials at a given crystal volume are obtained from first-principles density-functional calculations. The calculated chemical potentials are used to obtain the positron work function and deformation potential. The results are compared with previous calculations for several simple metals, and with experimental measurements of Al and Cu. 19 ref.--AA(US).
