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

Abstract

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)$$+11\atop{-10}$$(lit.) meV, respectively, where the last uncertainties are from adopted literature data. Finally, we use hydrodynamic nova simulations to model ²⁶Al production showing that these measurements effectively eliminate the dominant experimental nuclear-physics uncertainty and we estimate that novae may contribute up to 30% of the Galactic ²⁶Al.

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

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

Confirmation of a new resonance in ${}^{26}{Si}$ and contribution of classical novae to the galactic abundance of ${}^{26}{Al}$

Journal Article Canete, L. ; Doherty, D. T. ; Lotay, G. ; ... - Physical Review. C

The ²⁵Al(p, γ) reaction has long been highlighted as a possible means to bypass the production of ²⁶Al cosmic γ rays in classical nova explosions. However, uncertainties in the properties of key resonant states in ²⁶Si have hindered our ability to accurately model the influence of this reaction in such environments. We report on a detailed γ-ray spectroscopy study of ²⁶Si and present evidence for the existence of a new, likely l = 1, resonance in the ²⁵Al + p system at E_r = 153.9(15) keV. This state is now expected to provide the dominant contribution to the ²⁵Al(p, γ)more »« less

Determining the $r p$ -Process Flow through ${}^{56}{Ni}$ : Resonances in ${}^{57}{Cu} (p, γ) {}^{58}{Zn}$ Identified with GRETINA

Journal Article Langer, C. ; Montes, F. ; Aprahamian, A. ; ... - Physical Review Letters

An approach is presented in this paper to experimentally constrain previously unreachable (p,γ) reaction rates on nuclei far from stability in the astrophysical rp process. Energies of all critical resonances in the ⁵⁷Cu(p,γ)⁵⁸Zn reaction are deduced by populating states in ⁵⁸Zn with a (d,n) reaction in inverse kinematics at 75 MeV/u, and detecting γ-ray-recoil coincidences with the state-of-the-art γ-ray tracking array GRETINA and the S800 spectrograph at the National Superconducting Cyclotron Laboratory. The results reduce the uncertainty in the ⁵⁷Cu(p,γ) reaction rate by several orders of magnitude. Finally, the effective lifetime of ⁵⁶Ni, an important waiting point in the rpmore »« less
