Enhanced production of 60Fe in massive stars

A. Spyrou, D. Richman, A. Couture +23

Massive stars are a major source of chemical elements in the cosmos, ejecting freshly produced nuclei through winds and core-collapse supernova explosions into the interstellar med…

Independent Normalization for -ray Strength Functions: The Shape Method

M. Wiedeking, M. Guttormsen, A. C. Larsen +6

The Shape method, a novel approach to obtain the functional form of the -ray strength function (SF) in the absence of neutron resonance spacing data, is introduced. When used…

Novel Techniques for Constraining Neutron-Capture Rates Relevant for r-Process Heavy-Element Nucleosynthesis

A. C. Larsen, A. Spyrou, S. N. Liddick +1

The rapid-neutron capture process ( process) is identified as the producer of about 50\% of elements heavier than iron. This process requires an astrophysical environment with a…

Photoneutron cross sections for Ni isotopes: Toward understanding cross sections relevant to the weak s-process nucleosynthesis

H. Utsunomiya, T. Renstrøm, G. M. Tveten +19

Photoneutron cross sections were measured for Ni, Ni, Ni, and Ni at energies between the one-neutron and two-neutron thresholds using quasi-monochromati…

Completing the nuclear reaction puzzle of the nucleosynthesis of 92Mo

G. M. Tveten, A. Spyrou, R. Schwengner +20

One of the greatest questions for modern physics to address is how elements heavier than iron are created in extreme, astrophysical environments. A particularly challenging part of…

Low-energy enhancement in the γ-ray strength functions of Ge

T. Renstrøm, H. -T. Nyhus, H. Utsumoniya +22

The -ray strength functions and level densities of Ge have been extracted up to the neutron separation energy S from particle- coincidence data using the Oslo m…
