Implications for Type Ia Supernova Nucleosynthesis from an Experimentally Constrained $^{16}$ O $(p, I^\pm)^{13}$ N Reaction Rate

M. Alruwaili, C. Fougeres, A. M. Laird +13

The $^{16}$ O $(p, I^\pm)^{13}$ N reaction plays a key role in shaping the $I^\pm$ -particle abundance during explosive oxygen burning in Type Ia supernovae. By enhancing $I^\pm$ -production, thi…

First experimental determination of the $^{40}$ Ar( $n, 2 n$ ) $^{39}$ Ar reaction cross section and $^{39}$ Ar production in Earth's atmosphere

S. Bhattacharya, M. Paul, R. N. Sahoo +28

The cosmogenic $^{39}$ Ar(t $_{1/2}$ = 268 years) isotope of argon is used for geophysical dating and tracing owing to its appropriate half-life and chemical inertness as a noble gas;…

First measurement of 87Rb(Î±, xn) cross sections at weak r-process energies in supernova Î½-driven ejecta to investigate elemental abundances in low-metallicity stars

C. FougÃ¨res, M. L. Avila, A. Psaltis +18

Observed abundances of Z ~ 40 elements in metal-poor stars vary from star to star, indicating that the rapid and slow neutron capture processes may not contribute alone to the synt…
