In this work we study alpha-clustering in 18Ne and compare it with what is known about clustering in the mirror nucleus 18O. The excitation function of 18Ne was measured in inverse…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
Zn -delayed proton emission establishes the Ni -process waiting point bypass
M. Saxena, W. -J Ong, Z. Meisel +32
We measured the Zn -delayed proton (p) and emission at the National Superconducting Cyclotron Laboratory. We find a Zn half-life of 43.6 0.2 ms, p…
