energy range 12.6 ≤ E� ≤ 17.5 MeV and 11.5 ≤ E� ≤ 17.5 MeV, respectively, using the recently introduced method of combining activation with X-ray counting. Improved shielding allowed to measure the (�,) to lower energy than previously possible. The combination of (�,) and (�,n) data made it possible to study the energy dependence of thewidth. While absolute value and energy dependence are perfectly reproduced by theory at the energies above 14 MeV, the observed change in energy dependence at…

Measurement of (α,n) reaction crosssections of erbium isotopes for testingastrophysical rate predictions
The γ-process in core-collapse and/or type Ia supernova explosions is thought to explain the origin of the majority of the so-called p nuclei (the 35 protonrich isotopes between Se and Hg).
Uncertainties of α-particle optical potential assessment around and below the Coulomb barrier
A competition of the low-energy Coulomb excitation (CE) with the compound nucleus (CN) formation in α-induced reactions below the Coulomb barrier has recently been assumed in order to make possible
Constraining the astrophysical origin of the p-nuclei through nuclear physics and meteoritic data.
The main part of the review focuses on the nuclear uncertainties involved in the determination of the astrophysical reaction rates required for the extended reaction networks used in nucleosynthesis studies.
General properties of astrophysical reaction rates in explosive nucleosynthesis
Fundamental differences in the prediction of reaction rates with intermediate and heavy target nuclei compared to the ones with light nuclei are discussed, with special emphasis on stellar
