Total absorption gamma-ray spectroscopy is used to measure accurately the intensity of γ emission from neutron-unbound states populated in the β-decay of delayed-neutron emitters. From the comparison of this intensity with the intensity of neutron emission one can deduce information on the (n,γ ) cross section for unstable neutron-rich nuclei of interest in r process abundance calculations. A surprisingly large γ branching was observed for a number of isotopes. The results are compared with Hauser-Feshbach calculations and discussed.

Background: β-delayed multiple neutron emission has been observed for some nuclei with A≤100, being the Rb100 the heaviest β2n emitter measured to date. So far, only 25P2n values have been determined for the ≈300 nuclei ...
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 ...
Estimating Terrestrial Neutron-Induced SEB Cross-Sections and FIT Rates for High-Voltage SiC Power MOSFETs

(American Physical Society, 2024)

We investigated decays of 51,52,53K at the ISOLDE Decay Station at CERN in order to understand the mechanism of the 𝛽-delayed neutron-emission (𝛽⁢𝑛) process. The experiment quantified neutron and 𝛾-ray emission paths ...
The pion single-event latch-up cross-section enhancement : mechanisms and consequences for accelerator hardness assurance

Coronetti, Andrea; Alia Garcia, Ruben; Cerutti, Francesco; Hajdas, Wojtek; Söderström, Daniel; Javanainen, Arto; Saigne, Frederic (Institute of Electrical and Electronics Engineers (IEEE), 2021)

Pions make up a large part of the hadronic environment typical of accelerator mixed-fields. Characterizing device cross-sections against pions is usually disregarded in favour of tests with protons, whose single-event ...
