Measurement of the U fission cross section relative to the standard B(n, α) reaction at the CERN n_TOF facility: Results for E< 2 eV.

The neutron induced fission of U is a very important reaction for nuclear technology applications and for the design of future systems to produce clean and safe energy. In addition, it is used as a reference reaction for neutron cross-section measurements, thus, its cross section is needed with a high accuracy over a wide energy range. In this work, the measurement for the U(n,f) reaction was carried out at the n_TOF facility located at CERN, at experimental area EAR-2.

Neutron capture measurements for s-process nucleosynthesis: A review about CERN n_TOF developments and contributions.

This article presents a review about the main CERN n_TOF contributions to the field of neutron-capture experiments of interest for -process nucleosynthesis studies over the last 25 years, with a special focus on the measurement of radioactive isotopes. A few recent capture experiments on stable isotopes of astrophysical interest are also discussed. Results on -process branching nuclei are appropriate to illustrate how advances in detection systems and upgrades in the facility have enabled increasingly challenging experiments and, as a consequence, have led to a better understanding and modeling of the -process mechanism of nucleosynthesis.

Does Ultrasound Energy Applied During Phacoemulsification Influence the Thickness of Intraretinal Layers?

Phacoemulsification (PE) is a gold standard method of cataract surgery. PE causes structural changes in the macula of the eye. The aim was to determine the amount of ultrasound (US) energy applied during PE, the change in thickness of the intraretinal layers, and the correlation between the applied US energy and the change in the thickness of the intraretinal layers in five predefined areas of the macula.

Shedding Light on the Origin of ^{204}Pb, the Heaviest s-Process-Only Isotope in the Solar System.

Asymptotic giant branch stars are responsible for the production of most of the heavy isotopes beyond Sr observed in the solar system. Among them, isotopes shielded from the r-process contribution by their stable isobars are defined as s-only nuclei. For a long time the abundance of ^{204}Pb, the heaviest s-only isotope, has been a topic of debate because state-of-the-art stellar models appeared to systematically underestimate its solar abundance.
