The presented paper discusses the production of radioactive ion beams of francium, radium, and actinium from thick uranium carbide (UCx) targets at ISOLDE, CERN. This study focuses on the release curves and extractable yields of francium, radium and actinium isotopes. The ion source temperature was varied in order to study the relative contributions of surface and laser ionization to the production of the actinium ion beams. The experimental results are presented in the form of release parameters. Representative extractable yields per µC are presented for 222−231Ac, several Ra and Fr isotopes in the mass ranges 214≤A≤233 and 205≤A≤231 respectively. The release efficiency for several isotopes of each of the studied elements was calculated by comparing their yields to the estimated in-target production rates modeled by CERN-FLUKA. The maximal extraction efficiency of actinium was calculated to be 2.1(6)% for a combination of surface ionization using a Ta ion source and resonant laser io ... showmore

We measured absolute cross sections for neutron transfer channels populated in the 94Rb+208Pb binary reaction. Cross sections have been extracted identifying directly the lead isotopes with the high efficiency MINIBALL ...
Ion traps in nuclear physics : recent results and achievements

Eronen, Tommi; Kankainen, Anu; Äystö, Juha (Pergamon, 2016)

Ion traps offer a way to determine nuclear binding energies through atomic mass measurements with a high accuracy and they are routinely used to provide isotopically or even isomerically pure beams of short-living ions for ...
Nuclear physics of non-standard 0νβ β-decay

Kotila, J.; Graf, L.; Deppisch, F. F.; Iachello, F. (American Institute of Physics, 2019)

The observation neutrinoless double beta (0νβ β) decay remains crucial for understanding lepton number violation. In view of the difficulties to observe the mass mechanism of 0νβ β-decay, investigations of other mechanisms ...
Half-life determination of 215At and 221Ra with high-purity radioactive ion beams
