TL;DR: A mass measurement experiment by a time of flight method with the SPEG spectrometer at GANIL has been performed to investigate the N = 20 and N = 28 shell closures far from stability as mentioned in this paper.
Journal ArticleDOI
Precision measurement of the half-life and the decay branches of 62Ga
G. Canchel,B. Blank,Marielle Chartier,F. Delalee,Peter Dendooven,C. Dossat,J. Giovinazzo,Jussi Huikari,A. S. Lalleman,M. J. Lopez Jimenez,V. Madec,J. L. Pedroza,Heikki Penttilä,J. C. Thomas +13 more
TL;DR: In this article, the β-decay half-life of 62Ga has been studied with high precision using the IGISOL technique, where β-γ coincidences, the γ intensity of the 954 keV transition and an upper limit of the βdecay feeding of the 0+2 state have been extracted.
Journal ArticleDOI
Mass Measurements of Exotic Nuclei around N=Z=40 with CSS2
A. S. Lalleman,G. Auger,W. Mittig,M. Chabert,Marielle Chartier,J. Fermé,A. Gillibert,Alinka Lepine-Szily,M. Lewitowicz,M. H. Moscatello,N. A. Orr,G. Politi,F. Sarazin,H. Savajols,P. Van Isacker,A. C. C. Villari +15 more
TL;DR: In this article, mass measurements of the N = Z nuclei 80Zr, 76Sr, 68Se were performed for the first time and a new measurement was obtained for 80Y, using the second cyclotron CSS2 of GANIL as a high-resolution spectrometer.
