Dipole response in 208Pb within a self-consistent multiphonon approach

F. Knapp, N. Lo Iudice, P. Vesely +3

Background: The electric dipole strength detected around the particle threshold and commonly associated to the pygmy dipole resonance offers a unique information on neutron skin an…

A self-consistent study of multipole response in neutron-rich nuclei using a modified realistic potential

D. Bianco, F. Knapp, N. Lo Iudice +4

The multipole response of neutron rich O and Sn isotopes is computed in Tamm-Dancoff and random-phase approximations using the canonical Hartree-Fock-Bogoliubov quasi-particle basi…

An importance sampling algorithm for generating exact eigenstates of the nuclear Hamiltonian

F. Andreozzi, N. Lo Iudice, A. Porrino

We endow a recently devised algorithm for generating exact eigensolutions of large matrices with an importance sampling, which is in control of the extent and accuracy of the trunc…

Truncation of Large Shell-Model Eigenproblems by Model Space Partitioning

F. Andreozzi, A. Porrino

A method for solving the shell-model eigenproblem in a severely truncated space, spanned by properly selected correlated states obtained by partitioning the full configuration spac…

A simple iterative algorithm for generating selected eigenspaces of large matrices

F. Andreozzi, A. Porrino, N. Lo Iudice

We propose a new iterative algorithm for generating a subset of eigenvalues and eigenvectors of large matrices which generalizes the method of optimal relaxations. We also give con…

Proton Particle-Neutron Hole States in 132Sb with a Realistic Interaction

F. Andreozzi, L. Coraggio, A. Covello +3

The structure of the particle-hole nucleus 132Sb provides a direct source of information on the effective neutron-proton interaction in the 132Sn region. We have performed a shell-…
