Description
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 which are important due to the proximity of Z = 50, and masses of neutron-deficient Cd isotopes relevant for the magicity of N = 50.
Also 2008 gave us many very nice results: masses around Z=82 interesting for neutrino-mass determination; masses of 126,128Cd, 143-146Xe and 223-229Rn interesting for nuclear-structure questions: residual neutron-proton interaction reflected in the so called dVnp values, and compared to IBA calculations, and –presently ongoing- masses and trap-assisted decay spectroscopy on neutron-rich Hg isotopes. During our investigations we even discovered a new nuclide, 229Rn. The presentation will give a comprehensive review of the above results, followed by an outlook.
