1. Correlating nuclear masses, radii and E0 transitions

Piet Van Isacker (GANIL)

Improvements of the liquid-drop mass formula are proposed based on the introduction of (i) surface effects in the symmetry and Coulomb energies and (ii) shell effects through the counting of the number of valence nucleons. Inspired by these efforts, similar corrections in the description of nuclear radii are suggested. To include the influence of deformation on masses and radii requires...

22. Isoltrap harvest 2008

Dr Magdalena Kowalska (CERN)

The ISOLDE mass-spectrometer Isoltrap has recently successfully addressed a number of scientific highlights across the entire nuclear chart, among others: the question of proton-halo character of 17Ne, and the ``restoration'' of the 132,134Sn and 80,81Zn shell closures, of great relevance for the astrophysical r process. The latest results include masses of neutron-rich Ag and Cd isotopes...

Delahaye – ISOLDE/CERN The WITCH set-up (Weak Interaction Trap for Charged Particles) combines a double Penning trap system to store radioactive ions and a retardation spectrometer to probe the energy of the daughter...

21. Nuclear structure research and the discovery of a new isotope with the Penning trap mass spectrometer ISOLTRAP

In August 2008 the masses of neutron rich Xe and Rn isotopes were measured at the tandem Penning trap mass spectrometer ISOLTRAP with a relative mass precision down to a 1x10-8. During this online period the masses of 143-146Xe and 223-229Rn were measured, many of them for the first time directly. In addition the short-lived nuclide 229Rn has been observed for the very first time and aside of...
