Journal ArticleDOI

F. Hammache,G. Bogaert,P. Aguer,C. Angulo,S. Barhoumi,L. Brillard,J.F. Chemin,G. Claverie,A. Coc,M. Hussonnois,M. Jacotin,J. Kiener,A. Lefebvre,J. N. Scheurer,J. P. Thibaud,E. Virassamynaiken +15 more
TL;DR: In this article, the cross sections for the neutrino reaction have been measured for different beam conditions, different targets, and detectors, and the deduced zero-energy $S$ factor $S(0)$ is found to be 15% -20% smaller than the previously recommended value.
Journal ArticleDOI

TL;DR: The N = 28 shell closure has been investigated via the 46Ar(d,p)47Ar transfer reaction in inverse kinematics and a reduction of the N =28 gap is deduced by 330(90) keV and spin-orbit weakenings of approximately 10(2) and 45(10)% for the f and p states, respectively.
Journal ArticleDOI

TL;DR: A new experiment to determine the thermonuclear cross section of the C-12(alpha,gamma)O-16 reaction has been performed in regular kinematics using an intense alpha-particle beam of up to 340 mu A from the Stuttgart DYNAMITRON as mentioned in this paper.
Journal ArticleDOI

TL;DR: In this paper, the Trojan horse method is applied for the first time to a radioactive ion beam-induced reaction studying the reaction cross section at low energies relevant to astrophysics via the three-body reaction.
Journal ArticleDOI
Limited Asymmetry Dependence of Correlations from Single Nucleon Transfer
F. Flavigny,A. Gillibert,L. Nalpas,A. Obertelli,N. Keeley,Carlo Barbieri,D. Beaumel,S. Boissinot,G. Burgunder,Andrea Cipollone,A. Corsi,Julien Gibelin,S. Giron,J. Guillot,F. Hammache,V. Lapoux,A. Matta,E. C. Pollacco,Riccardo Raabe,M. Rejmund,N. de Séréville,A. Shrivastava,A. Signoracci,Yutaka Utsuno +23 more
TL;DR: The missing strength due to correlations does not show significant dependence on the nucleon separation energy asymmetry over a wide range of 37 MeV, in contrast with nucleon removal data analyzed within the sudden-eikonal formalism.
