Title: Sensitivity of the ¹³C(α,n)¹⁶O S factor to the uncertainty in the level parameters of the near-threshold state

Abstract

The ¹³C(α,n)¹⁶O reaction is the main source of neutrons for the s and i processes in asymptotic giant branch stars and carbon-enhanced metal-poor stars, respectively. The reaction rate over the relevant temperature range from 0.1 to 0.3 GK translates into a center-of-mass energy range of 150 to 540 keV. Current measurements extend down to 300 keV, still requiring an extrapolation of the cross section. At these low energies, the high-energy tail of a 1/2⁺ state near the reaction threshold makes a significant contribution to the cross section, but its amplitude is still highly uncertain. In this work the uncertainties associated with the low-energy cross-section extrapolation are investigated, in particular the sensitivity to the energy, width, and Coulomb renormalized asymptotic normalization coefficient of the near-threshold resonance. Furthermore, recently it has been suggested that the energy of the near-threshold level may have a large impact on the extrapolation, but this is not found to be the case compared with the other sources of uncertainty.

Determination of ${}^{20}{Ne} (p, γ) {}^{21}{Na}$ cross sections from $E_{p} = 500 - 2000 keV$

Journal Article Lyons, S. ; Görres, J. ; deBoer, R. J. ; ... - Physical Review C

Background: The reaction ²⁰Ne(p,γ) ²¹Na influences the nucleosynthesis of Ne, Na, and Mg isotopes while contributing to hydrogen burning in several stellar sites, such as red giants, asymptotic giant branch (AGB) stars, massive stars, and oxygen-neon (ONe) novae. In the relevant temperature range for these environments (T = 0.05–0.5 GK), the main contributions to this reaction rate are from the direct capture process as well as the high-energy tail of a subthreshold resonance in the ground-state transition at E_x = 2425 keV in the ²¹Na compound nucleus. Purpose: The previous measurement of this reaction reports cross sections with large uncertaintiesmore »« less

Low-energy cross-section measurement of the ${}^{10}B (α, n) {}^{13}N$ reaction and its impact on neutron production in first-generation stars

Journal Article Liu, Q. ; Febbraro, M. ; deBoer, R. J. ; ... - Physical Review. C

Nucleosynthesis in the first generation of massive stars offers a unique setting to explore the creation of the first heavier nuclei in an environment free of impurities from earlier stellar generations. In later generations of massive stars, hydrogen burning occurs predominantly through the CNO cycles, but without the carbon, nitrogen, and oxygen to catalyze the reaction sequence, first stars would have to rely on the inefficient pp chains for their energy production. Observations of second and third generation stars show pronounced abundances of carbon and oxygen isotopes, which suggests a rapid conversion of the primordial abundances to heavier elements.

New ¹³C(α,n)¹⁶O Cross Section with Implications for Neutrino Mixing and Geoneutrino Measurements

Journal Article Febbraro, M. ; deBoer, R. J. ; Pain, S. D. ; ... - Physical Review Letters

Precise antineutrino measurements are very sensitive to proper background characterization. Here, we present an improved measurement of the ¹³C(α,n)¹⁶O reaction cross section which constitutes significant background for large v¯ detectors. We greatly improve the precision and accuracy by utilizing a setup that is sensitive to the neutron energies while making measurements of the excited state transitions via secondary γ-ray detection. Our results shows a 54% reduction in the background contributions from the ¹⁶O(3–, 6.13 MeV) state used in the KamLAND analysis.

First near-threshold measurements of the ¹³C($α, n$₁) ¹⁶O reaction for low-background-environment characterization

Journal Article deBoer, R. J. ; Gula, A. ; Febbraro, Michael T. ; ... - Physical Review. C

The modeling of background sources in large volume detection systems requires accurate nuclear cross sections for a variety of reactions. Among the most important are (α,n) on light nuclei, where α particles, up to ≈9 MeV, are produced from the decay of actinides present in trace amounts in detection and structural material. In order to model the neutron energy spectra and production of other secondary particles, the partial cross sections are needed. Yet very little experimental data exists for these partial cross sections because past measurements, hampered by the experimental challenges of neutron detection, have focused mostly on total reactionmore »« less
