The Isoscalar Giant Dipole Resonance: Where we are and where we are headed

Abstract

Over the past few years, very good evidence has emerged for the Isoscalar Giant Dipole Resonance from small-angle inelastic scattering of α particles between 50–100 MeV/nucleon. A reconciliation between the available theoretical predictions and the experimental results still remains far from satisfactory, however, and there are interesting implications of the observed ISGDR strengths on the experimental determination of the incompressibility of nuclear matter. Some possible future measurements are also discussed.
