Direct measurement of F()Ne cross sections with ANASEN
K. S. Davis, J. C. Blackmon, C. M. Deibel +21
The F()Ne reaction may impact Asymptotic Giant Branch nucleosynthesis and helium burning on accreting white dwarfs. This reaction has never been directly measure…
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;…
Valence proton vacancy of the Si ground state
N. Watwood, C. R. Hoffman, B. P. Kay +22
The Si(He,)P reaction was studied in inverse kinematics at 6.3~MeV/. States in P corresponding to the proton single-particle orbitals were id…
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…
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…
Evolution of the nuclear spin-orbit splitting explored via the Si(,)Si reaction using SOLARIS
J. Chen, B. P. Kay, C. R. Hoffman +30
The spin-orbit splitting between neutron 1 orbitals at Si has been deduced using the single-neutron-adding (,) reaction in inverse kinematics with a beam of …
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…
Measurement of fragment-correlated -ray emission from Cf(sf)
Stefano Marin, Ivan A. Tolstukhin, Nathan P. Giha +3
This paper presents recent experimental results on the yield of prompt fission rays from the spontaneous fission of Cf. We use an ionization chamber to tag fission even…
