Neutron capture reactions play a crucial role for the understanding of the synthesis of elements heavier than iron in stars and stellar explosions via the slow (s), intermediate (i), and rapid (r) neutron capture processes. In all three processes, the fine balance between neutron capture and beta-decay rates under the given astrophysical conditions defines how long a nucleus can accumulate...

5. Surrogate reactions in inverse kinematics at heavy-ion storage rings

In this contribution, I will present the NECTAR project, which uses for the first time surrogate reactions in inverse kinematics at a heavy-ion storage ring. This allows one to measure all the de-excitation probabilities as a function of the excitation energy of the nuclei formed through the surrogate reaction with unrivaled efficiency and precision, and to indirectly determine neutron-induced...

1. High accuracy measurements of neutron induced cross sections on short-lived nuclei at the CERN n_TOF facility

The n_TOF facility houses CERN’s pulsed neutron source, comprising two beam lines of different flight paths (at ≈185 and ≈19 m) and one activation station. It is driven by the 20 GeV proton beam delivered by the Proto-Synchrotron accelerator impinging on a lead spallation target.
The energy resolution and the high instantaneous neutron flux are key factors to increase the...
