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 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…
Meaurement of spin vs. TKE of Ba produced in spontaneous fission of Cf
N. P. Giha, S. Marin, I. A. Tolstukhin +21
We measure the average spin of Ba, a common fragment produced in Cf(sf), as a function of the total kinetic energy (TKE). We combined for the first time a twin Fris…
