Secondary Neutron Production from Thick Target Deuteron Breakup
Jonathan T. Morrell, Andrew S. Voyles, Jon C. Batchelder +2
Thick target deuteron breakup is a variable-energy accelerator-based source of high-energy neutrons, with applications in fundamental and applied nuclear science and engineering. H…
Measurement and Modeling of Proton-Induced Reactions on Arsenic from 35 to 200 MeV
Morgan B. Fox, Andrew S. Voyles, Jonathan T. Morrell +10
As is a promising positron emitter for diagnostic imaging that can be employed locally using a Se generator. However, current reaction pathways to Se have insu…
Investigating High-Energy Proton-Induced Reactions on Spherical Nuclei: Implications for the Pre-Equilibrium Exciton Model
Morgan B. Fox, Andrew S. Voyles, Jonathan T. Morrell +10
A number of accelerator-based isotope production facilities utilize 100- to 200-MeV proton beams due to the high production rates enabled by high-intensity beam capabilities and th…
An Integral Experiment on Polyethylene Using Radiative Capture in Indium Foils in a High Flux D-D Neutron Generator
Nnaemeka Nnamani, Karl van Bibber, Lee A Bernstein +2
The Department of Nuclear Engineering, University of California Berkeley built a D-D neutron generator called the High Flux Neutron Generator (HFNG). It operates in the range of 10…
Measurement of La(p,x) Cross Sections from 35-60 MeV by Stacked-Target Activation
Jonathan T. Morrell, Andrew S. Voyles, M. S. Basunia +3
A stacked-target of natural lanthanum foils (99.9119% La) was irradiated using a 60 MeV proton beam at the LBNL 88-Inch Cyclotron. La(p,x) cross sections are report…
Measurement of the Zn,Ti(n,p) Cross Sections using a DD Neutron Generator for Medical Isotope Studies
Andrew Voyles, M. S. Basunia, Jon Batchelder +8
Cross sections for the Ti(n,p)Sc and Zn(n,p)Cu reactions have been measured for quasi-monoenergetic DD neutrons produced by the UC Berkeley High Flux Ne…
Orbital dependent nucleonic pairing in the lightest known isotopes of tin
Iain G. Darby, Robert K. Grzywacz, Jon C. Batchelder +13
By studying the 109Xe-->105Te-->101Sn superallowed alpha-decay chain, we observe low-lying states in 101Sn, the one-neutron system outside doubly magic 100Sn. We find that the spin…
The Single-Particle Structure of Neutron-Rich Nuclei of Astrophysical Interest at the Ornl Hribf
D. W. Bardayan, J. C. Batchelder, J. C. Blackmon +19
The rapid nuetron-capture process (r process) produces roughly half of the elements heavier than iron. The path and abundances produced are uncertain, however, because of the lack…
