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…
Excitation functions for (p,x) reactions of niobium in the energy range of E = 40-90 MeV
Andrew S. Voyles, Lee A. Bernstein, Eva R. Birnbaum +5
A stack of thin Nb foils was irradiated with the 100 MeV proton beam at Los Alamos National Laboratory's Isotope Production Facility, to investigate the Nb(p,4n)Mo nu…
Nuclear excitation functions from 40-200 MeV proton irradiation of terbium
Jonathan W. Engle, Stepan G. Mashnik, Lauren A. Parker +8
Nuclear formation cross sections are reported for 26 radionuclides, measured with 40 to 200 MeV proton irradiations of terbium foils. These data are relevant to the production of m…
Fission Fragments Produced from Proton Irradiation of Thorium Between 40 and 200 MeV
Jonathan W. Engle, Stepan G. Mashnik, John W. Weidner +9
The cross sections for the formation of five residual radionuclides (72Se, 97Zr, 112Pd, 125Sb, and 147Nb) from 40- to 200-MeV proton irradiation of thorium have been measured and a…
Cross sections from proton irradiation of thorium at 800 MeV
Jonathan W. Engle, Stepan G. Mashnik, John W. Weidner +11
Nuclear formation cross sections are reported for 65 nuclides produced from 800-MeV proton irradiation of thorium foils. These data are useful as benchmarks for computational predi…
Cross Sections from 800 MeV Proton Irradiation of Terbium
J. W. Engle, S. G. Mashnik, H. Bach +13
A single terbium foil was irradiated with 800 MeV protons to ascertain the potential for production of lanthanide isotopes of interest in medical, astrophysical, and basic science…
Proton-induced cross sections relevant to production of 225Ac and 223Ra in natural thorium targets below 200 MeV
