The pygmy quadrupole resonance and neutron-skin modes in 124Sn

The pygmy quadrupole resonance and neutron-skin modes in 124Sn

We present an extensive experimental study of the recently predicted pygmy quadrupole resonance (PQR) in Sn isotopes, where complementary probes were used. In this study, (α,α′γ) and (γ,γ′) experiments were performed on 124Sn. In both reactions, Jπ=2+ states below an excitation energy of 5 MeV were...
