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 ab…
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…
Double-beta decay Q values of 130Te, 128Te, and 120Te
N. D. Scielzo, S. Caldwell, G. Savard +13
The double-beta decay Q values of 130Te, 128Te, and 120Te have been determined from parent-daughter mass differences measured with the Canadian Penning Trap mass spectrometer. 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 …
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…
Elastic scattering of 3He+4He with SONIK
S. N. Paneru, C. R. Brune, D. Connolly +22
Measurements of the elastic scattering cross section of 3He and 4He are important in order to improve constraints on theoretical models of 4He(3He,g)7Be, a key reaction in Big Bang…

We have performed the first direct measurement of two resonances of the Be()C reaction with unknown strengths using an intense radioactive Be beam and the DRA…
Mass measurements of neutron-rich Rb and Sr isotopes
R. Klawitter, A. Bader, M. Brodeur +16
We report on the mass measurements of several neutron-rich and isotopes in the region with the TITAN Penning-trap mass spectrometer. Usi…
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}} =…
A direct measurement of the 17O(a,g)21Ne reaction in inverse kinematics and its impact on heavy element production
M. P. Taggart, C. Akers, A. M. Laird +33
During the slow neutron capture process in massive stars, reactions on light elements can both produce and absorb neutrons thereby influencing the final heavy element abundances. A…
The nuclear force imprints revealed on the elastic scattering of protons with C
A. Kumar, R. Kanungo, A. Calci +26
How does nature hold together protons and neutrons to form the wide variety of complex nuclei in the universe? Describing many-nucleon systems from the fundamental theory of quantu…
C+O sub-barrier radiative capture cross-section measurements
A. Goasduff, S. Courtin, F. Haas +11
We have performed a heavy ion radiative capture reaction between two light heavy ions, C and O, leading to Si. The present experiment has been performed below…
