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…
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…
Restricted spin-range correction in the Oslo Method: The example of nuclear level density and -ray strength function from
F. Zeiser, G. M. Tveten, G. Potel +19
The Oslo Method has been applied to particle- coincidences following the (d,p) reaction to obtain the nuclear level density (NLD) and -ray strength functio…
Nuclear level densities and gamma-ray strength functions of Ta
C. P. Brits, K. L. Malatji, M. Wiedeking +24
Particle- coincidence experiments were performed at the Oslo Cyclotron Laboratory with the Ta(d,X) and Ta(He,X) reactions, to measure the nuclear level den…
Impact of restricted spin-ranges in the Oslo Method: The example of (d,p)
F. Zeiser, G. Potel, G. M. Tveten +18
In this paper we present the first systematic analysis of the impact of the populated vs. intrinsic spin distribution on the nuclear level density and -ray strength function ret…
First experimental constraint on the Os reaction rate relevant to -process nucleosynthesis
I. K. B. Kullmann, A. C. Larsen, T. Renstrø m +10
The nuclear level density and -decay strength of Os have been extracted using particle- coincidence data from the Os()Os reaction by mean…
Nuclear level densities and -ray strength functions of -- First application of the Oslo Method in inverse kinematics
V. W. Ingeberg, S. Siem, M. Wiedeking +26
The -ray strength function (SF) and nuclear level density (NLD) have been extracted for the first time from inverse kinematic reactions with the Oslo Method. This novel techn…
Gamma-widths, lifetimes and fluctuations in the nuclear quasi-continuum
M. Guttormsen, A. C. Larsen, J. E. Midtbø +8
Statistical -decay from highly excited states is determined by the nuclear level density (NLD) and the -ray strength function (SF). These average quantities have been meas…
Energy dependence of the prompt -ray emission from the -induced fission of and
S. J. Rose, F. Zeiser, J. N. Wilson +22
Prompt fission -rays are responsible for approximately 5\% of the total energy released in fission, and therefore important to understand when modelling nuclear reactors. In thi…
Low-energy enhancement and fluctuations of -ray strength functions in Fe: test of the Brink-Axel hypothesis
A. C. Larsen, M. Guttormsen, N. Blasi +21
Nuclear level densities and -ray strength functions of Fe have been extracted from proton- coincidences. A low-energy enhancement in the -ray strength functions…
