Abstract
Positron states in the BEDT-TTF based organic superconduCtors, namely kappa-Cu(NCS)2, kappa-CuCN[N(CN)2] and kappa-Cu[N(CN)2]Br salts, have been calculated using the superposed-atom model and the numerical rela xation technique. For each salt, positrons are distributed predominant ly around the anion layers and have a little overlap with the TTF skel eton and the outer S atoms which are responsible for the conductivity.
