0 State in 18O by using Core – Polarization effects

Abstract

Coulomb form factors for E0 transition in 18O are discussed taking into account core-polarization effects. These effects are taken into account through the collective model of Tassie and also through a microscopic perturbation theory including excitations up to 2p1f shell. Space wave model functions defined for the orbits and are obtained from the diagonalization of the interaction Hamilonian of Wildenthal. The calculations include the 0 state with excitation energies 3.6337MeV. The core – polarization effects which incorporate the collective model of Tassei describe the data very well for this state.
