Title: Key ${}^{19}{Ne}$ States Identified Affecting $γ$ -Ray Emission from ${}^{18}F$ in Novae

Abstract

Detection of nuclear-decay γ rays provides a sensitive thermometer of nova nucleosynthesis. The most intense γ-ray flux is thought to be annihilation radiation from the β⁺ decay of ¹⁸F, which is destroyed prior to decay by the ¹⁸F(p,α)¹⁵O reaction. Estimates of ¹⁸F production had been uncertain, however, because key near-threshold levels in the compound nucleus, ¹⁹Ne, had yet to be identified. We report the first measurement of the ¹⁹F(³He,tγ)¹⁹Ne reaction, in which the placement of two long-sought 3/2⁺ levels is suggested via triton-γ–γ coincidences. Furthermore, the precise determination of their resonance energies reduces the upper limit of the rate by a factor of 1.5–17 at nova temperatures and reduces the average uncertainty on the nova detection probability by a factor of 2.1.

New $γ$ -ray transitions observed in ${}^{19}{Ne}$ with implications for the ${}^{15}O (α, γ) {}^{19}{Ne}$ reaction rate

Journal Article Hall, Matt R. ; Bardayan, D. W. ; Baugher, T. ; ... - Physical Review C

The O-15(alpha, gamma)(19) Ne reaction is responsible for breakout from the hot CNO cycle in type I x-ray bursts. Understanding the properties of resonances between E-x = 4 and 5 MeV in Ne-19 is crucial in the calculation of this reaction rate. The spins and parities of these states are well known, with the exception of the 4.14-and 4.20-MeV states, which have adopted spin-parities of 9/2(-) and 7/2(-) respectively. gamma-ray transitions from these states were studied using triton-gamma-gamma coincidences from the F-19(He-3, t gamma)(19) Ne reaction measured with the GODDESS (Gammasphere ORRUBA Dual Detectors for Experimental Structure Studies) at Argonnemore »« less

Study of the ${}^{26}{Al}^{m} (d, p) {}^{27}{Al}$ Reaction and the Influence of the ${}^{26}{Al}$ $0^{+}$ Isomer on the Destruction of ${}^{26}{Al}$ in the Galaxy

Journal Article Almaraz-Calderon, S. ; Rehm, K. E. ; Gerken, N. ; ... - Physical Review Letters

The existence of ²⁶Al (t_1/2 = 7.17 × 10⁵ yr) in the interstellar medium provides a direct confirmation of ongoing nucleosynthesis in the Galaxy. The presence of a low-lying 0⁺ isomer (²⁶Al^m), however, severely complicates the astrophysical calculations. Here we present for the first time a study of the ²⁶Al^m (d, p)²⁷ Al reaction using an isomeric ²⁶Al beam. The selectivity of this reaction allowed the study of ℓ = 0 transfers to T = 1/2, and T = 3/2 states in ²⁷Al . Mirror symmetry arguments were then used to constrain the ²⁶Al ^m (p,γ) ²⁷Si reaction rate andmore »« less

Decays of the Three Top Contributors to the Reactor ${\bar{ν}}_{e}$ High-Energy Spectrum, ${}^{92}{Rb}$ , ${}^{96 gs}Y$ , and ${}^{142}{Cs}$ , Studied with Total Absorption Spectroscopy

Journal Article Rasco, B. C. ; Wolińska-Cichocka, M. ; Fijałkowska, A. ; ... - Physical Review Letters

Here, we report total absorption spectroscopy measurements of ⁹²Rb, ⁹⁶^gsY, and ¹⁴²Cs β decays, which are the most important contributors to the high energy ν¯_e spectral shape in nuclear reactors. These three β decays contribute 43% of the ¯νe flux near 5.5 MeV emitted by nuclear reactors. This ν¯_e energy is particularly interesting due to spectral features recently observed in several experiments including the Daya Bay, Double Chooz, and RENO Collaborations. Measurements were conducted at Oak Ridge National Laboratory by means of proton-induced fission of ²³⁸U with on-line mass separation of fission fragments and the Modular Total Absorption Spectrometer.

Constraint of the Astrophysical ${}^{26 g}{Al} (p, γ) {}^{27}{Si}$ Destruction Rate at Stellar Temperatures

Journal Article Pain, S. D. ; Bardayan, D. W. ; Blackmon, J. C. ; ... - Physical Review Letters

The Galactic 1.809-MeV γ-ray signature from the β decay of ^26gAl is a dominant target of γ-ray astronomy, of which a significant component is understood to originate from massive stars. The ^26gAl(p,g)27Si reaction is a major destruction pathway for ^26gAl at stellar temperatures, but the reaction rate is poorly constrained due to uncertainties in the strengths of low-lying resonances in ²⁷Si. The ^26gAl(d,p)²⁷Al reaction has been employed in inverse kinematics to determine the spectroscopic factors, and hence resonance strengths, of proton resonances in ²⁷Si via mirror symmetry. Furthermore, the strength of the 127-keV resonance is found to be a factormore »« less

Classical-Nova Contribution to the Milky Way’s ${}^{26}{Al}$ Abundance: Exit Channel of the Key ${}^{25}{Al} (p, γ) {}^{26}{Si}$ Resonance

Journal Article Bennett, M. B. ; Wrede, C. ; Chipps, K. A. ; ... - Physical Review Letters

We present that classical novae are expected to contribute to the 1809-keV Galactic γ-ray emission by producing its precursor ²⁶Al, but the yield depends on the thermonuclear rate of the unmeasured ²⁵Al(p,γ)²⁶Si reaction. Using the β decay of ²⁶P to populate the key J^π=3⁺ resonance in this reaction, we report the first evidence for the observation of its exit channel via a 1741.6±0.6(stat)±0.3(syst) keV primary γ ray, where the uncertainties are statistical and systematic, respectively. By combining the measured γ-ray energy and intensity with other experimental data on ²⁶Si, we find the center-of-mass energy and strength of the resonance to be E_r=414.9±0.6(stat)±0.3(syst)±0.6(lit.) keV and ωγ=23±6(stat)more »« less
