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…
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…
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…
The gamma-ray strength function of Y and Y
G. M. Tveten, T. Renstrøm, A. C. Larsen +26
In this work, we present new data on the Y(,n) cross section studied with a quasi-monochromatic photon beam produced at the NewSUBARU synchrotron radiation facility in Ja…
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…
La(, ) cross sections constrained with statistical decay properties of La nuclei
Bonginkosi Vincent Kheswa, Mathis Wiedeking, Josh Brown +22
The nuclear level densities and -ray strength functions of La were measured using the La(He, ), La(He, He) and $^{1…
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…
The structure of low-lying states in Sm studied by Coulomb excitation
M. Klintefjord, K. Hadyńska-Klȩk, A. Görgen +41
The electromagnetic structure of Sm was studied in a low-energy Coulomb excitation experiment with a radioactive ion beam from the REX-ISOLDE facility at CERN. The an…
Statistical properties of Pu, and Pu(n,) cross section calculation
T. A. Laplace, F. Zeiser, M. Guttormsen +24
The level density and gamma-ray strength function (gammaSF) of 243Pu have been measured in the quasi-continuum using the Oslo method. Excited states in 243Pu were populated using t…
Experimentally constrained ()Y and ()Y reaction rates relevant to the -process nucleosynthesis
A. C. Larsen, M. Guttormsen, R. Schwengner +18
The nuclear level density and the -ray strength function have been extracted for Y, using the Oslo Method on Y()Y coincidence data. The -ray stre…
Experimental level densities of atomic nuclei
M. Guttormsen, M. Aiche, F. L. Bello Garrote +24
It is almost 80 years since Hans Bethe described the level density as a non-interacting gas of protons and neutrons. In all these years, experimental data were interpreted within t…
Shell-gap reduced level densities in Y
M. Guttormsen, A. C. Larsen, F. L. Bello Garrote +14
Particle- coincidences from the Y()Y and Y()Y reactions were utilized to obtain -ray spectra as function of excitation energy. The…
Level densities and thermodynamical properties of Pt and Au isotopes
F. Giacoppo, F. L. Bello Garrote, L. A. Bernstein +15
The nuclear level densities of Pt and Au below the neutron separation energy have been measured using transfer and scattering reactions. All the level densi…
Observation of double pygmy resonances in Pt and enhanced astrophysical reaction rates
F. Giacoppo, F. L. Bello Garrote, T. K. Eriksen +12
Our measurements of Pt -strength functions show a double-humped enhancement in the MeV region. For the first time, the detailed shape of these resonances…
