First direct measurement of Cu(p,)Ni: A step towards constraining the Ni-Cu cycle in the Cosmos
J. S. Randhawa, R. Kanungo, J. Refsgaard +34
Reactions on the proton-rich nuclides drive the nucleosynthesis in Core-Collapse Supernovae (CCSNe) and in X-ray bursts (XRBs). CCSNe eject the nucleosynthesis products to the inte…
Constraining the Ne(,)Mg and Ne(,n)Mg reaction rates using sub-Coulomb -transfer reactions
H. Jayatissa, G. V. Rogachev, V. Z. Goldberg +9
The Ne(,)Mg and Ne(,n)Mg reactions play an important role in astrophysics because they have significant influence on the neutron flux during th…
Decay properties of resonances and their impact on -process nucleosynthesis
S. Ota, G. Christian, G. Lotay +15
The astrophysical -process is one of the two main processes forming elements heavier than iron. A key outstanding uncertainty surrounding -process nucleosynthesis is the neut…
Observation of excited states in Mg sheds light on nuclear forces and shell evolution
J. S. Randhawa, R. Kanungo, M. Holl +35
The exotic Borromean nucleus Mg with = 8, located at the proton drip-line provides a unique testing ground for nuclear forces and the evolution of shell structure in the…
Direct Measurement of Astrophysically Important Resonances in
G. Christian, G. Lotay, C. Ruiz +12
According to sensitivity studies, the reaction has a significant influence on , , and p…
Measurement of Lifetimes in 23Mg
O. S. Kirsebom, P. Bender, A. Cheeseman +22
Several lifetimes in 23Mg have been determined for the first time using the Doppler-shift attenuation method. A Monte Carlo simulation code has been written to model the gamma-ray…
Three-body correlations in the ground-state decay of 26O
Z. Kohley, T. Baumann, G. Christian +10
Background: Theoretical calculations have shown that the energy and angular correlations in the three-body decay of the two-neutron unbound O26 can provide information on the groun…
Search for unbound 15Be states in the 3n+12Be channel
A. N. Kuchera, A. Spyrou, J. K. Smith +10
15Be is expected to have low-lying 3/2+ and 5/2+ states. A first search did not observe the 3/2+ [A. Spyrou et al., Phys. Rev. C 84, 044309 (2011)], however, a resonance in 15Be wa…
Exploiting neutron-rich radioactive ion beams to constrain the symmetry energy
Z. Kohley, G. Christian, T. Baumann +8
The Modular Neutron Array (MoNA) and 4 Tm Sweeper magnet were used to measure the free neutrons and heavy charged particles from the radioactive ion beam induced 32Mg + 9Be reactio…
Strength of the keV resonance in {Ne}{Na}
G. Christian, D. Hutcheon, C. Akers +3
The NeNa reaction is the starting point of the NeNa cycle, which is an important process for the production of intermediate mass elements. The $E_{\text{cm}} =…
Novel techniques to search for neutron radioactivity
M. Thoennessen, G. Christian, Z. Kohley +5
Two new methods to observe neutron radioactivity are presented. Both methods rely on the production and decay of the parent nucleus in flight. The relative velocity measured betwee…
Search for C and constraints on C
S. Mosby, N. S. Badger, T. Baumann +20
A search for the neutron-unbound nucleus C was performed via the single proton removal reaction from a beam of 22 N at 68 MeV/u. Neutrons were detected with the Modular Neut…
Study of two-neutron radioactivity in the decay of 26O
Z. Kohley, T. Baumann, D. Bazin +12
A new technique was developed to measure the lifetimes of neutron unbound nuclei in the picosecond range. The decay of 26O -> 24O+n+n was examined as it had been predicted to have…
First observation of Li ground state
Z. Kohley, E. Lunderberg, P. A. DeYoung +16
The ground state of neutron-rich unbound Li was observed for the first time in a one-proton removal reaction from Be at a beam energy of 53.6 MeV/u. The Li gro…
Exploring the neutron dripline two neutrons at a time: The first observations of the 26O and 16Be ground state resonances
Z. Kohley, A. Spyrou, E. Lunderberg +22
The two-neutron unbound ground state resonances of O and Be were populated using one-proton knockout reactions from F and B beams. A coincidence measure…
Spectroscopy of neutron-unbound F
G. Christian, N. Frank, S. Ash +16
The ground state of F has been observed as an unbound resonance keV above the ground state of F. Comparison of this result with USDA/USDB shell mode…
