Calculation of positron characteristics for elements of the periodic table

摘要: Positron characteristics have been calculated in bulk and monovacancies for most of the elements periodic table. Self-consistent non-self-consistent schemes used calculation electronic structure solid, different parametrizations positron enhancement factor correlation energy. As it is known, lifetimes show a behaviour with atomic number. These calculations also confirm that monovacancy follow same behaviour. The results obtained compared selected experimental lifetime data, which confirms theoretical trends. binding energies to energy shows number too.
