CADEIA and REJECT are computer codes for generating γ-γ and γ-X true-coincidence lines for calculation of correction factors for absolute counting of gamma rays in a low energy photon detector. They are written in FORTRAN 77. True-coincidence lines are generated by CADEIA; they are submitted to selection by REJECT according to the rejection criteria defined by L. Moens et al. and F. De Corte. Final relevant lines for true-coincidence correction factors are given as output of REJECT.
