摘要: Abstract The CEPA equations are derived and the connections between CI or MBPT procedures discussed in detail. A new self-consistent direct method (SCD) is proposed to treat which include: complete CI(SD), CEPA, MP-PT (3rd order), of Bartlett Silver as special cases. Applications prove excellent quality versions CEPA(1) CEPA(2).
