Mass measurements of neutron-rich nuclei near the N = 20 and 28 shell closures
B. Jurado,H. Savajols,W. Mittig,N. A. Orr,P. Roussel-Chomaz,D. Baiborodin,W. N. Catford,Marielle Chartier,C. E. Demonchy,Z. Dlouhý,A. Gillibert,Lydie Giot,A. Khouaja,Alinka Lepine-Szily,S. M. Lukyanov,J. Mrazek,Y. E. Penionzhkevich,S. Pita,M. Rousseau,Antonio Villari +19 more
TL;DR: In this article, mass measurements of very neutron-rich nuclei near the N = 20 and 28 shell closures are presented, where seven masses have been determined for the first time and the precision of 36 masses has been significantly improved.
Journal ArticleDOI

TL;DR: The ratio of neutron to proton contributions to the 2(1)+ state is found close to the N/Z ratio, demonstrating a strong N = 14 shell closure in the vicinity of the neutron drip line.
Journal ArticleDOI
MAYA: an Active-Target Detector for Binary Reactions with Exotic Beams
C. E. Demonchy,M. Caamaño,He Wang,Wolfgang Mittig,P. Roussel-Chomaz,H. Savajols,Marielle Chartier,D. Cortina-Gil,A. S. Fomichev,G. Frémont,P. Gangnant,A. Gillibert,Lydie Giot,M. S. Golovkov,B. Jurado,J. F. Libin,A. Obertelli,E. Pollaco,A. M. Rodin,Ch. Spitaels,S. V. Stepantsov,G. M. Ter-Akopian,R. Wolski +22 more
TL;DR: In this article, the authors developed a new active target detector for low-intensity and low-energy secondary beams based on the active target concept, which allows to use a relatively thick target without loss of resolution by using the detection gas as target material.
Journal ArticleDOI
Resonance state in 7H.
M. Caamaño,M. Caamaño,D. Cortina-Gil,W. Mittig,H. Savajols,Marielle Chartier,C. E. Demonchy,B. Fernandez,M. B. Gomez Hornillos,A. Gillibert,Beatriz Jurado,O. Kiselev,Roy Crawford Lemmon,A. Obertelli,F. Rejmund,M. Rejmund,P. Roussel-Chomaz,R. Wolski +17 more
TL;DR: This study represents an unambiguous proof of the existence of the most neutron-proton unbalanced system presently found.
Journal ArticleDOI
MAYA, a gaseous active target
C. E. Demonchy,W. Mittig,H. Savajols,P. Roussel-Chomaz,Marielle Chartier,B. Jurado,Lydie Giot,D. Cortina-Gil,M. Caamaño,G. Ter-Arkopian,A. S. Fomichev,A. M. Rodin,M. S. Golovkov,S. V. Stepantsov,A. Gillibert,E. C. Pollacco,A. Obertelli,He Wang +17 more
TL;DR: In this paper, the active target concept is used to increase the reaction rates with a thick target, without loss of resolution, and the MAYA detector is developed, which is essentially a Time-charge Projection chamber where the gas plays also the role of the target.
