Strahlungseinfangreaktionen für die nukleare Astrophysik und die Energiekalibration von Ionenbeschleunigern

Autor: Rümmler, S.

Ein präzises Verständnis über die Entstehung der Elemente im Universum stellt ein hoch- relevantes Kernthema der nuklearen Astrophysik dar. Vor diesem Hintergrund wurde die 12C(p,γ)13N-Reaktion untersucht, die als Startreaktion des CNO-Zyklus Ein

We have discovered a presolar olivine from ALH 77307 with the highest ^25 Mg isotopic composition measured in a silicate to date ( δ ^25 Mg = 3025.1‰ ± 38.3‰). Its isotopic compositions challenge current stellar models, with modeling of magnesi

The 18O(p,α)15N reaction affects the synthesis of 15N, 18O and 19F isotopes, whose abundances can be used to probe the nucleosynthesis and mixing processes occurring deep inside asymptotic giant branch (AGB) stars. We performed a low-background dire
