Abstract

The pseudopotential picture of the positron in a binary alloy is developed. It is shown that the positron is usually preferentially attracted to one sort of atom in the alloy. This relative positron affinity is associated with the positron pseudopotential difference between the different sorts of atom and calculations of this quantity are presented for a number of 50 at % alloys.
