## Abstract In this paper a calculation of the static quadrupole polarizabilities and the shielding factors of the atoms and ions of the 2__p__ open shell systems is presented. A fully coupled Hartree–Fock method using the Roothaan formalism is adopted. Calculations have been done for the ground as
The open-shell coupled-cluster method IS applied to 21 SIZG of C. 0, O2 and their ION\_ Only two-electron excitations (T2) are taken into account Good agreement with experiment (better than 0.2 eV) is obtamed for the ten excitation enerwes and seven of the eight ionization potentials cakulaled. tie
## Abstract Static dipole polarizabilities and shielding factors for the 2__p__ open shell atomic systems are presented using coupled Hartree Fock theory in the framework of the Roothaan formalism. Calculations have been performed for the ground as well as for some valence excited states. A variati
