Abstract

Multi-step cascade γ-ray spectra from the neutron capture at isolated resonances of 161Dy nucleus were measured at the LANSCE/DANCE time-of-flight facility in Los Alamos National Laboratory. The objectives of this experiment were to confirm and possibly extend the spin assignment of s-wave neutron resonances and get new information on photon strength functions with emphasis on the role of the M1 scissors mode vibration. The preliminary results show that the scissors mode plays a significant role in all transitions between accessible states of the studied nucleus. The photon strength functions describing well our data are compared to results from 3He-induced reactions, (n,γ) experiments on Gd isotopes, and (γ,γ’) reactions.

Scissors mode of Gd nuclei studied from resonance neutron capture

Journal Article Kroll, J ; Baramsai, B ; Becker, J A ; ... - AIP Conference Proceedings

Spectra of {gamma} rays following the neutron capture at isolated resonances of stable Gd nuclei were measured. The objectives were to get new information on photon strength of {sup 153,155-159}Gd with emphasis on the role of the M1 scissors-mode vibration. An analysis of the data obtained clearly indicates that the scissors mode is coupled not only to the ground state, but also to all excited levels of the nuclei studied. The specificity of our approach ensures unbiasedness in estimating the sumed scissors-mode strength {Sigma}B(M1){up_arrow}, even for odd product nuclei, for which conventional nuclear resonance fluorescence measurements yield only limited information.more »« less

The study of scissors mode excitations in [sup 162,164]Dy by inelastic neutron scattering

Miscellaneous Johnson, E L

Low-energy collective excitations in nuclei arising from the explicit inclusion of separate proton and neutron degrees of freedom have been predicted within the framework of various nuclear models. In well-deformed even-even nuclei, those isovector excitations appear at excitation energies near 3 MeV, have spin and parity J[sup [pi]] = 1[sup +], and exhibit a B(M1) strength of [approximately]2-3 [mu][sub N][sup 2]. The geometrical intepretation of the excitation as an out-of-phase angular oscillation of the protons versus the neutrons has naturally led to the designation scissors mode' for these states. Scissors mode states have been experimentally observed in deformed nuclei rangingmore »« less
Review of Livermore-Led Neutron Capture Studies Using DANCE

Conference Parker, W ; Sheets, S ; Agvaanluvsan, U ; ...

We have made neutron capture cross-section measurements using the white neutron source at the Los Alamos Science Center, the DANCE detector array (Detector for Advanced Neutron Capture Experiments) and targets important for basic science and stockpile stewardship. In this paper, we review results from (n,{gamma}) reactions on {sup 94,95}Mo, {sup 152,154,157,160,nat}Gd, {sup 151,153}Eu and {sup 242m}Am for neutron energies from < 1eV up to {approx} 20 keV. We measured details of the {gamma}-ray cascade following neutron capture, for comparison with results of statistical model simulations. We determined the neutron energy dependent (n,{gamma}) cross section and gained information about statistical decaymore »« less

Evidence for the Scissors Mode in {sup 160}Tb from the Two-Step Gamma Cascades Measurement

Journal Article Kroll, J ; Becvar, F ; Krticka, M ; ... - AIP Conference Proceedings

Spectra of two-step {gamma} cascades (TSCs) following the neutron capture in {sup 159}Tb were measured by the sum-coincidence technique with a two-HPGe-detector facility [1] installed at a pure sub-thermal neutron beam of the 15 MW light-water research reactor at Rez near Prague. In order to obtain information about the quantities governing the {gamma} decay of {sup 160}Tb levels--the photon strength functions (PSFs) and the level density (LD)--experimental TSC spectra were compared with the output of simulations of the {gamma} cascade decay based on the validity of extreme statistical model. These simulations were performed with the aid of the DICEBOX algorithmmore »« less
