Implications for Type Ia Supernova Nucleosynthesis from an Experimentally Constrained ON Reaction Rate
M. Alruwaili, C. Fougeres, A. M. Laird +13
The ON reaction plays a key role in shaping the -particle abundance during explosive oxygen burning in Type Ia supernovae. By enhancing -production, this r…
The impact of O reaction rate uncertainties on the s-process in rotating massive stars
J. Frost-Schenk, P. Adsley, A. M. Laird +9
Massive stars are crucial to galactic chemical evolution for elements heavier than iron. Their contribution at early times in the evolution of the Universe, however, is unclear due…
Narrow resonances in the continuum of the unbound nucleus F
V. Girard-Alcindor, A. Mercenne, I. Stefan +100
The structure of the unbound F nucleus is investigated using the inverse kinematics resonant scattering of a radioactive O beam impinging on a CH target. The anal…
New experimental Na()Mg Reaction Rate for Massive Star and Type-Ia Supernova models
N. J. Hubbard, C. Aa. Diget, S. P. Fox +8
The Na()Mg reaction has been identified as having a significant impact on the nucleosynthesis of several nuclei between Ne and Ti in type-Ia supernovae, and of $…
Single-particle structure in neutron-rich Sr isotopes approaching the N = 60 shape transition
S. Cruz, K. Wimmer, S. S. Bhattacharjee +33
Background: Neutron-rich nuclei around neutron number N = 60 show a dramatic shape transition from spherical ground states to prolate deformation in 98Sr and heavier nuclei. Purpos…

Single-Particle Structure of Neutron-Rich Sr Isotopes Via d( 94,95,96 Sr, p) Reactions
S. Cruz, K. Wimmer, P. C. Bender +32
The region around neutron number N = 60 in the neutron-rich Sr and Zr nuclei is one of the most dramatic examples of a ground state shape transition from (near) spherical below N =…
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…
One-proton and one-neutron knockout reactions from Ni to the mirror pair Co and Ni
M. Spieker, A. Gade, D. Weisshaar +15
We present a high-resolution in-beam -ray spectroscopy study of excited states in the mirror nuclei Co and Ni following one-nucleon knockout from a projectile beam…
Shell evolution approaching the N=20 island of inversion: Structure of 29Mg
A. Matta, W. N. Catford, N. A. Orr +36
The "Island of Inversion" for neutron-rich nuclei in the vicinity of N=20 has become the testing ground par excellence for our understanding and modelling of shell evolution with i…
Shape Coexistence and Mixing of Low-Lying States in Sr
S. Cruz, P. C. Bender, R. Krücken +32
The low energy excited states in Sr are amongst the most prominent examples of shape coexistence across the nuclear landscape. In this work, the neutron $[2s_{1/…
