Nuclear Level Density and -ray Strength Function of and the impact on the i-process
V. W. Ingeberg, S. Siem, M. Wiedeking +29
Proton- coincidences from reactions between a beam and a deuterated polyethylene target have been analyzed with the inverse-Oslo met…
Strong enhancement of level densities in the crossover from spherical to deformed neodymium isotopes
M. Guttormsen, Y. Alhassid, W. Ryssens +19
Understanding the evolution of level densities in the crossover from spherical to well-deformed nuclei has been a long-standing problem in nuclear physics. We measure nuclear level…
A novel approach for extracting model-independent nuclear level densities far from stability
D. Mücher, A. Spyrou, M. Wiedeking +22
The level density of quantum states in statistical mesoscopic systems is a critical input for various fields of physics, including nuclear physics, nuclear astrophysics, atomic phy…
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…
The energy response of the Oslo Scintillator Array OSCAR
F. Zeiser, G. M. Tveten, F. L. Bello Garrote +5
The new Oslo Scintillator Array (OSCAR) has been commissioned at the Oslo Cyclotron Laboratory (OCL). It consists of 30 large volume (diameter 3.5 x 8 inches) LaBr(Ce) detector…
Simultaneous determination of neutron-induced fission and radiative-capture cross sections from decay probabilities obtained with a surrogate reaction
R. Perez Sanchez, B. Jurado, V. Meot +20
Reliable neutron-induced reaction cross sections of unstable nuclei are essential for nuclear astrophysics and applications but their direct measurement is often impossible. The su…
