Implications for Type Ia Supernova Nucleosynthesis from an Experimentally Constrained ON Reaction Rate
M. Alruwaili, C. Fougeres, A. M. Laird +13
The ON reaction plays a key role in shaping the -particle abundance during explosive oxygen burning in Type Ia supernovae. By enhancing -production, this r…
Detailed Study of the Cu(p,Ni Reaction and Constraints on Its Astrophysical Reaction Rate
E. Lopez-Saavedra, M. L. Avila, W. -J. Ong +20
The CuNi reaction plays an important role in explosive astrophysical scenarios such as Type I X-ray bursts and the -process in neutrino-driven winds followin…
Direct Measurement of the CuNi Excitation Function to Constrain the Ni--Cu Cycle Strength and Its Impact on Explosive Nucleosynthesis
E. Lopez-Saavedra, M. L. Avila, W. -J. Ong +21
A new direct measurement of the 59Cu(p,a)56Ni excitation function from 2.43-5.88 MeV in the center-of-mass was performed in inverse kinematics using the high-efficiency MUSIC activ…
First experimental determination of the Ar()Ar reaction cross section and Ar production in Earth's atmosphere
S. Bhattacharya, M. Paul, R. N. Sahoo +28
The cosmogenic Ar(t= 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;…
Quenching of single-particle strength inferred from nucleon-removal transfer reactions on C
Y. C. Jiang, J. Chen, B. P. Kay +24
The difference in the proton and neutron separation energies () of the weakly bound C ground state is -19.86 MeV, an extreme value. Data from intermediate-energy heavy-i…
First measurement of 87Rb(α, xn) cross sections at weak r-process energies in supernova ν-driven ejecta to investigate elemental abundances in low-metallicity stars
C. Fougères, 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…
Direct cross-section measurement of the weak r-process 88Sr(α,n)91Zr reaction in ν-driven winds of core collapse supernovae
C. Fougères, M. L. Avila, H. Jayatissa +15
About half of the heavy elements beyond iron are known to be produced by the rapid neutron capture process, known as r-process. However, the astrophysical site producing the r-proc…
Study of the Mg waiting point relevant for x-ray burst nucleosynthesis via the Mg(,)Al reaction
H. Jayatissa, M. L. Avila, K. E. Rehm +13
The Mg(,)Al reaction rate has been identified as a major source of uncertainty for understanding the nucleosynthesis flow in Type-I x-ray bursts (XRBs). We repo…
