Håkan Danared,G. Andler,L. Bagge,C.J. Herrlander,J. Hilke,J. Jeansson,Anders Källberg,A. Nilsson,A. Paál,K.-G. Rensfelt,U. Rosengård,J. Starker,M. af Ugglas +12 more
TL;DR: In this article, an electron beam expanded by a factor of 10 has been implemented at the CRYRING electron cooler, decreasing the transverse electron temperature from 100 to 10 meV.
Journal ArticleDOI

K. Abrahamsson,G. Andler,L. Bagge,E. Beebe,P. Carle,Håkan Danared,S. Egnell,K. Ehrnsten,M. Engström,C.J. Herrlander,J. Hilke,J. Jeansson,Anders Källberg,S. Leontein,L. Liljeby,A. Nilsson,A. Paál,K.-G. Rensfelt,U. Rosengård,Ansgar Simonsson,A. Soltan,J. Starker,M. af Ugglas,A. Filevich +23 more
TL;DR: In this paper, a small synchrotron and storage ring equipped with electron cooling is described, where highly charged ions from the electron beam ion source CRYSIS are injected via an RFQ into the ring.

TL;DR: In this paper, the electromagnetic properties and the calculated level energies require the following configurations: using the magnetic moments and transition probabilities of the relevant levels the mixing amplitudes are estimated and it is found that relatively small admixtures are important for the understanding of the experimentally determined electromagnetic properties.
Journal ArticleDOI
Investigation of the high-spin structure of 200,202Pb
TL;DR: In this paper, the yrast structure of 200,202Pb was studied using the in-beam γ-ray spectrosopic methods including γγ(t) coincidence, pulsed-beam and angular distribution measurements, and the measured g-factors indicate a predominantly four-quasineutron configuration ν f 5 2 −1 i 13 2 −3 for the 19− isomeric states.
Journal ArticleDOI
YRAST spectroscopy and g-factor measurements in 199Pb, 201Pb and 203Pb
U. Rosengård,P. Carlé,A. Källberg,Lars-Olov Norlin,K. G. Rensfelt,H. C. Jain,B. Fant,T. Weckström +7 more
TL;DR: In this paper, the half-lives and g-factors of high-spin states in 199,201,203pb were studied using 199,200,202Hg(α, 3n) reactions at Eα =41 and 53 MeV.
