New experimental constraint on the W()W cross section
A. C. Larsen, G. M. Tveten, T. Renstrøm +28
In this work, we present new data on the W() cross sections, utilizing a quasi-monochromatic photon beam produced at the NewSUBARU synchrotron radiation facili…
Evolution of the -ray strength function in neodymium isotopes
M. Guttormsen, K. O. Ay, M. Ozgur +24
The experimental gamma-ray strength functions (gamma-SFs) of 142,144-151Nd have been studied for gamma-ray energies up to the neutron separation energy. The results represent a uni…
Statistical properties of the well deformed Sm nuclei and the scissors resonance
K. L. Malatji, K. S. Beckmann, M. Wiedeking +18
The Nuclear Level Densities (NLDs) and the -ray Strength Functions (SFs) of Sm have been extracted from (d,p) coincidences using the Oslo method. The experimen…
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…
First evidence of enhanced low-energy -ray strength from thermal neutron capture data
L. Crespo Campo, R. B. Firestone, B. A. Brown +2
The -ray strength function, or average reduced -ray transition probability, is a fundamental input in the calculation of cross sections used to simulate the nucleosyn…

Enhanced low-energy -decay strength of Ni and its robustness within the shell model
A. C. Larsen, J. E. Midtbø, M. Guttormsen +19
Neutron-capture reactions on very neutron-rich nuclei are essential for heavy-element nucleosynthesis through the rapid neutron-capture process, now shown to take place in neutron-…
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…
