This review paper concerns the research devoted to the study of the properties of dipole
excitations in nuclei. The main focus is on questions related to isospin effects in these types …

This review aims at giving a critical description of the theoretical researches conducted on
the low-lying dipole states traditionally denoted as Pygmy Dipole Resonances (PDR). A brief …

The pygmy dipole resonance in neutron-rich nuclei is studied within the framework of the
Vlasov equation, which is solved numerically. The interaction used in the Thomas-Fermi …

We study heavy-ion inelastic scattering processes in neutron-rich nuclei including the full
response to the different multipolarities. Among these we focus in particular on the excitation …

We study the correlation between the neutron skin development and the low-energy dipole
response associated with the pygmy dipole resonance (PDR) in connection with the …

We study the low-energy dipole (LED) strength distribution along the Sn isotopic chain in
both the isoscalar (IS) and the isovector (IV, or E 1) electric channels, to provide testable …

A very important open question related to the pygmy dipole resonance refers to its quite
elusive collective nature. In this paper, within a harmonic oscillator shell model, generalizing …

It is shown that the use of a proper form factor in the study of the pygmy dipole resonance
(PDR) is of paramount importance in order to determine the correct values for the relevant …

The worldwide advent of new laser facilities makes possible the investigation of the nuclear
response to a very strong electromagnetic field. In this paper, we inquire on the excitation of …

In 16 O and 40 Ca an isoscalar, low-energy dipole transition (IS-LED) exhausting
approximately 4% of the isoscalar dipole (ISD) energy-weighted sum rule is experimentally …
