Approximate method for calculating the lifetime of positrons trapped by lattice defects

Conference ·
OSTI ID:7124430
;
A method which takes account of core as well as valence electrons is presented for theoretically estimating the life-time of positrons trapped in lattice defects. The method is illustrated by calculations for vacancies and divacancies in aluminum.
