Charge exchange excitation in nuclei

Description

We study charge-exchange transitions in exotic nuclei. The ground state is calculated with a HFB ansatz which is then used to calculate the charge exchange excitations by a QRPA calculation. We use an extended QRPA ansatz which, besides pairing effects, also accounts for the coupling to the continuum and dissipative contributions. The spectral distributions and transition probabilities are extracted from the polarization propagator. The polarization propagator is calculated by solving directly the Dyson-equation. Results of 56Fe for natural and unnatural parity excitations are discussed. Applications to neutrino scattering are indicated.
