This page gives hints on how to set parameters for a calculation with a positron in the system with the ABINIT package.
|
|
|
|
## Introduction
|
|
|
|
The lifetime of a positron, its annihilation rate and other associated properties can be computed, using
|
|
the self-consistent two-component DFT formalism, including force and stress computation (and thus relaxation),
|
|
LDA and GGA, wirhin norm-conserving pseudopotentials as well as PAW approach [[cite:Wiktor2015]].
|
|
|
|
Doppler broadening can also be computed. The details of the way to perform such
|
|
calculations are given in the description of the [[positron]] input variable,
|
|
as well as in [[tutorial:positron|the tutorial on electron-positron
|
|
annihilation]].
|
|
|
|
Examples can be found in [[cite:Wiktor2013]], [[cite:Wiktor2014]],
|
|
[[cite:Wiktor2014a]] and [[cite:Wiktor2014b]].
