On the robustness of surface vibrational modes: case studies in the Cd region

Recent studies of the stable Cd isotopes, using inelastic neutron scattering, radioactive decay and nucleon-transfer reactions, have resulted in the need to fundamentally reassess the concept of low-energy vibrational modes in these isotopes. We present a synopsis of the nuclear physics that has led...

Description
Summary:Recent studies of the stable Cd isotopes, using inelastic neutron scattering, radioactive decay and nucleon-transfer reactions, have resulted in the need to fundamentally reassess the concept of low-energy vibrational modes in these isotopes. We present a synopsis of the nuclear physics that has led to this situation, followed by the present status of spectroscopy for and against vibrational modes in nuclei neighbouring the Cd isotopes. We continue with some details of the spectroscopic techniques used and examples of the data obtained which lead to the above statements. We provide further perspective with some details of octupole degrees of freedom. We conclude with an outlook of where spectroscopic data are needed to further assess the presence or absence of low-energy vibrations in nuclei; and we provide some reflections on where future theoretical investigations should be directed.
