Exploration for Astromers near Sn with the Canadian Penning Trap
A. A. Valverde, S. Cupp, A. Gross +26
Nuclear isomers can have significant impacts on astrophysical nucleosynthesis processes, with recent efforts demonstrating that the population of isomeric states with different hal…
ENDF/B-VIII.1: Updated Nuclear Reaction Data Library for Science and Applications
G. P. A. Nobre, R. Capote, M. T. Pigni +106
The ENDF/B-VIII.1 library is the newest recommended evaluated nuclear data file by the Cross Section Evaluation Working Group (CSEWG) for use in nuclear science and technology appl…
Reducing parametric uncertainties through information geometry methods
M. Imbrišak, A. E. Lovell, M. R. Mumpower
Information geometry is a study of applying differential geometry methods to challenging statistical problems, such as uncertainty quantification. In this work, we use information…
An optical-lensing inspired data thinning method for nuclear cross section data
M. Imbrišak, A. E. Lovell, M. R. Mumpower
In the study of nuclear cross sections, the computational demands of data assimilation methods can become prohibitive when dealing with large data sets. We have developed a novel v…
Weighted Levenberg-Marquardt methods for fitting multichannel nuclear cross section data
M. Imbrišak, A. E. Lovell, M. R. Mumpower
We present an extension of the Levenberg-Marquardt algorithm for fitting multichannel nuclear cross section data. Our approach offers a practical and robust alternative to conventi…
Astrophysical significance of the isomer Ag demonstrated through direct mass measurement
F. Rivero, M. Brodeur, J. A. Clark +18
The abundance of elements heavier than iron produced via the astrophysical rapid-neutron capture process depends sensitively on the atomic mass of the involved nuclei as well as th…
Beta delayed neutron emission of Cd
M. Madurga, Z. Y. Xu, 1 R. Grzywacz +54
Using the time-of-flight technique, we measured the beta-delayed neutron emission of Cd. From our large-scale shell model (LSSM) calculation using the NLO interaction […
Novel Application of Neutrinos to Evaluate U.S. Nuclear Weapons Performance
J. R. Distel, E. C. Dunton, J. M. Durham +10
There is a growing realization that neutrinos can be used as a diagnostic tool to better understand the inner workings of a nuclear weapon. Robust estimates demonstrate that an Inv…
The Los Alamos evaluation of Pu neutron-induced reactions in the fast energy range
M. R. Mumpower, D. Neudecker, T. Kawano +5
A major revision of the evaluation of Pu neutron-induced reaction cross sections is reported in the fast energy range. The evaluation starts at 2.5 keV incident neutron ene…
Nuclear data activities for medium mass and heavy nuclei at Los Alamos
M. R. Mumpower, T. M Sprouse, T. Kawano +7
Nuclear data is critical for many modern applications from stockpile stewardship to cutting edge scientific research. Central to these pursuits is a robust pipeline for nuclear mod…
Physically Interpretable Machine Learning for nuclear masses
