The performance of the Gamma-Ray Energy Tracking In-beam Nuclear Array GRETINA
Stefanos Paschalis,I. Y. Lee,A. O. Macchiavelli,C. M. Campbell,M. Cromaz,S. Gros,J. Pavan,J. Qian,R. M. Clark,H. L. Crawford,Dionisio Doering,P. Fallon,C. Lionberger,T. Loew,Marina Petri,T. Stezelberger,S. Zimmermann,D. C. Radford,K. Lagergren,D. Weisshaar,R. Winkler,T. Glasmacher,J. T. Anderson,C. W. Beausang +23 more
TL;DR: The Gamma-Ray Energy Tracking In-beam Nuclear Array (GRETINA) as mentioned in this paper is a new generation high-resolution γ - ray spectrometer consisting of electrically segmented high-purity germanium crystals.
Journal ArticleDOI
Reduction of spectroscopic strength: Weakly-bound and strongly-bound single-particle states studied using one-nucleon knockout reactions
Alexandra Gade,P. Adrich,D. Bazin,M. D. Bowen,B. A. Brown,C. M. Campbell,J. M. Cook,T. Glasmacher,P. G. Hansen,K. E. Hosier,S. McDaniel,D. McGlinchery,A. Obertelli,K. Siwek,L. A. Riley,J. A. Tostevin,D. Weisshaar +16 more
TL;DR: In this paper, both one-proton and one-neutron knockout reactions were performed with fast beams of two asymmetric, neutron-deficient rare isotopes produced by projectile fragmentation, which were used to probe the nucleon spectroscopic strengths at both the weakly and strongly bound nucleon Fermi surfaces.
Journal ArticleDOI
Enhanced quadrupole collectivity at N = 40: the case of neutron-rich Fe isotopes.
W. Rother,A. Dewald,H. Iwasaki,S. M. Lenzi,K. Starosta,D. Bazin,T.R. Baugher,B. A. Brown,Hl Crawford,C. Fransen,Alexandra Gade,Tn Ginter,T. Glasmacher,Gf Grinyer,M. Hackstein,G. Ilie,J. Jolie,S. McDaniel,David Miller,P. Petkov,T. Pissulla,A. Ratkiewicz,Ca Ur,P. Voss,Ka Walsh,D. Weisshaar,Ko Zell +26 more
TL;DR: The trend of collectivity suggested by the experimental data is described by state-of-the-art shell-model calculations with a new effective interaction developed for the fpgd valence space.
Journal ArticleDOI
Quadrupole collectivity in neutron-rich Fe and Cr isotopes.
H. L. Crawford,R. M. Clark,P. Fallon,A. O. Macchiavelli,T.R. Baugher,D. Bazin,C. W. Beausang,J. S. Berryman,D. L. Bleuel,C. M. Campbell,M. Cromaz,G. de Angelis,Alexandra Gade,Richard Hughes,I. Y. Lee,S. M. Lenzi,Frédéric Nowacki,Stefanos Paschalis,Marina Petri,Alfredo Poves,A. Ratkiewicz,T. J. Ross,E. Sahin,D. Weisshaar,Kathrin Wimmer,R. Winkler +25 more
TL;DR: The results are compared to state-of-the-art large-scale shell-model calculations within the full fpgd neutron orbital model space using the Lenzi-Nowacki-Poves-Sieja effective interaction and confirm the results of the calculations that show these nuclei are well deformed.
Journal ArticleDOI

Voulot,N. Warr,D. Weisshaar,F. Wenander,M. Zielińska +33 more
TL;DR: In this paper, the reduced transition probabilities of the radioactive isotopes (108,106)Sn using subbarrier Coulomb excitation at the REX-ISOLDE facility at CERN were measured.
