Branching ratio Γα/Γγ of the 4.033 MeV 3/2+ state in 19Ne Open
The branching ratio Γα/Γγ of the 4.033 MeV 3/2+ state in 19Ne plays a crucial role in the breakout from the hot CNO cycle into the rapid proton capture process. This ratio has been studied by making use of the advantages of inverse kinemat…

Experimental study of the Ni56(He3,d)Cu57 reaction in inverse kinematics Open
Measurements of (He3,d) reactions can provide information on the proton widths of states that play a role in astrophysically important (p,γ) reactions. We report on the first study of the (He3,d) reaction in inverse kinematics with a Ni56(…

New determination of the astrophysical S factor SE1 of the C12(α,γ)O16 reaction Open
A new measurement of the β-delayed α decay of N16 has been performed using a set of high efficiency ionization chambers. Sources were made by implantation of a N16 beam, yielding very clean α spectra down to energies as low as 400 keV. Our…

Spectroscopic data, such as precise γ-ray branching and E 2/ M 1 multipole-mixing ratios, provide vital constraints when performing multi-dimensional Coulomb-excitation analyses. Consequently, as part of our new Coulomb-excitation campaign…
Fusion-induced fission measurements with the MUSIC active target detector Open
The rapid neutron capture process ( r-process ) is believed to be responsible for about half of the production of the elements heavier than iron and it may also contribute to abundances of some lighter nuclides. Great excitement was recent…
Review of high intensity ion source development and operation Open
The Electron Cyclotron Resonance Ion Source (ECRIS) has transformed the nuclear physics research field over the last 47 years. Today, the performance of ion sources is the first parameter that defines the design performance of existing fac…
