Nuclear level densities and gamma-ray strength functions in 44,45Sc
A. C. Larsen, M. Guttormsen, R. Chankova +8
The scandium isotopes 44,45Sc have been studied with the 45Sc(3He,alpha gamma)44Sc and 45Sc(3He,3He' gamma)45Sc reactions, respectively. The nuclear level densities and gamma-ray s…
Test of nuclear level density inputs for Hauser-Feshbach model calculations
A. V. Voinov, S. M. Grimes, C. R. Brune +3
The energy spectra of neutrons, protons, and alpha-particles have been measured from the d+59Co and 3He+58Fe reactions leading to the same compound nucleus, 61$Ni. The experimental…
Establishment of M1 multipolarity of a 6.5 mu_N^2 resonance in 172-Yb at E_gamma=3.3 MeV
A. Schiller, A. Voinov, E. Algin +7
Two-step-cascade spectra in 172-Yb have been measured after thermal neutron capture. They are compared to calculations based on experimental values of the level density and radiati…
Evolution of level density step structures from 56,57-Fe to 96,97-Mo
A. Schiller, E. Tavukcu, L. A. Bernstein +9
Level densities have been extracted from primary gamma spectra for 56,57-Fe and 96,97-Mo nuclei using (3-He,alpha gamma) and (3-He,3-He') reactions on 57-Fe and 97-Mo targets. The…
Measurements of Nuclear Level Densities and Gamma-Ray Strength Functions and their Interpretations
M. Guttormsen, M. Hjorth-Jensen, J. Rekstad +3
A method to extract primary -ray spectra from particle- coincidences at excitation energies up to the neutron binding energy is described. From these spectra, the level densi…
Observation of the scissors mode in the quasicontinuum
A. Schiller, M. Guttormsen, E. Melby +3
The experimental resonance parameters of the pygmy resonance in rare earth nuclei are compared to global parameters of the scissors-mode states. It is argued that the pygmy resonan…
