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 follow…
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;…
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…
