Probing the Size of Neutron and Proton Single-Particle Orbitals from Nucleon Knockout Reactions

M. Enciu, A. Obertelli, P. Doornenbal +83

The size of neutron and proton single-particle orbitals of Ca, Ca, Ca, and Sc were investigated via nucleon knockout reactions at 230 MeV/nucleon…

The dipole strength distribution of He and decay characteristics

C. Lehr, T. Aumann, M. Duer +91

The weak binding and spatially extended neutron densities characteristic of drip-line nuclei give rise to a distinctive low-energy dipole response. The drip-line nucleus He is…

Spectroscopy of deeply bound orbitals in neutron-rich Ca isotopes

P. J. Li, J. Lee, P. Doornenbal +85

The calcium isotopes are an ideal system to investigate the evolution of shell structure and magic numbers. Although the properties of surface nucleons in calcium have been well st…
