Background. The R-Matrix formalism is a crucial tool in the study of nuclear astrophysics reactions, and many codes have been written to implement the relevant mathematics. One such code makes use of Visual Basic macros. A further open-source code, A

With the R$^{3}$B-LAND setup at GSI we have measured exclusive relative-energy spectra of the Coulomb dissociation of $^{18}$C at a projectile energy around 425~AMeV on a lead target, which are needed to determine the radiative neutron-capture cross

Publikováno v: Physical Review C. 93

The neutron capture cross sections of light nuclei ($Al56$) are important for $s$-process scenarios since they act as neutron poisons. We report on measurements of the neutron capture cross sections of $^{41}\mathrm{K}$ and $^{45}\mathrm{Sc}$, which

Publikováno v: Physical Review C. 93

Background: The CNO cycle is the main energy source in stars more massive than our sun; it defines the energy production and the cycle time that lead to the lifetime of massive stars, and it is an important tool for the determination of the age of gl

An 60Fe target for studying the 60Fe(n, γ)61Fe cross-section at stellar energies was prepared using radio-chemical separation techniques. In total, 7.8×1015 60Fe atoms (777 ng) were separated from a copper beam dump for the 590 MeV proton beam of t
