A. Lennarz,M. Williams,M. Williams,Alison Laird,U. Battino,A. Chen,D. Connolly,Barry Davids,N. E. Esker,R. Garg,Uwe Greife,U. Hager,D. A. Hutcheon,Jordi José,M. Lovely,Stephanie Lyons,Stephanie Lyons,A. Psaltis,J. Riley,A. Tattersall,Chris Ruiz +20 more
TL;DR: In this paper, the first inverse kinematics measurement of key resonances in the Ne 22 (p, γ ) 23 Na reaction was reported, which is relevant for 23Na synthesis in asymptotic giant branch (AGB) stars.

Jennifer Fallis,C. Akers,C. Akers,Alison Laird,Anna Simon,A. Spyrou,G. Christian,D. Connolly,U. Hager,D. A. Hutcheon,A. Lennarz,Patrick O'Malley,S. J. Quinn,J. Riley,A. Rojas,Chris Ruiz,M. Williams,M. Williams +17 more
TL;DR: In this paper, the first cross section measurements of the 76Se( α, γ )80Kr reaction were performed in inverse kinematics in the energy region of the photo-disintegration pathway and compared with cross sections calculated using Hauser-Feshbach codes talys, non-smoker, and smaragd.

First measurement of the S 34 ( p , γ ) Cl 35 reaction rate through indirect methods for presolar nova grains
S. Gillespie,Anuj Parikh,C. J. Barton,T. Faestermann,Jordi José,Ralf Hertenberger,H.-F. Wirth,N. de Séréville,J. Riley,M. Williams,M. Williams +10 more
TL;DR: In this paper, the S-34(He-3,d)Cl-35 reaction at 20 MeV was measured using a high resolution quadrupole-dipole-diagonal-deconvex-diphysics-based magnetic spectrograph.

TL;DR: In this article, the existence and the nature of these sub-threshold states were investigated at the Tandem-ALTO facility using the $18}$F(p,$\alpha$)$^{15}$O reaction rate which, despite many experimental and theoretical efforts, still remains uncertain.
