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…

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…
Design and commissioning of a timestamp-based data acquisition system for the DRAGON recoil mass separator
G. Christian, C. Akers, D. Connolly +4
The DRAGON recoil mass separator at TRIUMF exists to study radiative proton and alpha capture reactions, which are important in a variety of astrophysical scenarios. DRAGON experim…
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…
Constraining nova observables: direct measurements of resonance strengths in 33S(p,γ)34Cl
J. Fallis, A. Parikh, P. F. Bertone +32
The 33S(p,γ)34Cl reaction is important for constraining predictions of certain isotopic abundances in oxygen-neon novae. Models currently predict as much as 150 times the solar abu…
