Isospin splitting of the giant dipole resonance in 60Ni
Abstract
The most stringent test to date of the concept of isospin splitting of the giant dipole resonance in a medium-weight nucleus has been performed by a study of the (γ, n0), (γ, p0), and (γ, γ) reaction channels for 60Ni. The ground-state photoneutron cross section for 60Ni was measured and compared with the already known (γ, p0) reaction cross section in order to demonstrate isospin splitting. The relative strength and separation of the isospin-dependent components of the resonance were estimated from an analysis of photon scattering data.
