Two neutrino double beta decay within the -approximation
C. Barbero, F. Krmpotić, A. Mariano
We examine the contributions of odd-parity nuclear operators to the two-neutrino double beta decay amplitude, which come from the -wave Coulomb corrections…

Ground-state Correlation Effects in Extended RPA Calculations
A. Mariano, F. Krmpotić, A. F. R. de Toledo Piza
We study normalization problems associated with use of perturbatively correlated ground-states in extended RPA schemes in the context of a specific but typical example. The sensiti…

On the energy-shell contributions of the three-particle~-~ three-hole excitations
A. Mariano, F. Krmpotić, A. F. R. de Toledo Piza
The response functions for the extended second and third random phase approximation are compared. A second order perturbation calculation shows that the first-order amplitude for t…
