Journal ArticleDOI
Plans for the creation and studies of electron-positron plasmas in a stellarator
T. Sunn Pedersen,J. R. Danielson,Christoph Hugenschmidt,Gerrit Marx,X. Sarasola,Felix Schauer,Lutz Schweikhard,Clifford M Surko,E Winkler +8 more
TL;DR: In this article, the authors present plans for the creation and diagnosis of pair plasmas in a stellarator, based on extrapolation of the results from the Columbia Non-neutral Torus stellarator.
Journal ArticleDOI
Probing the N=32 Shell Closure below the Magic Proton Number Z=20: Mass Measurements of the Exotic Isotopes ^{52,53}K.

TL;DR: The recently confirmed neutron-shell closure at N=32 has been investigated for the first time below the magic proton number Z=20 with mass measurements of the exotic isotopes (52,53)K, highlighting the doubly magic nature of this nuclide.
Journal ArticleDOI
Mass Measurements of Very Neutron-Deficient Mo and Tc Isotopes and Their Impact on rp Process Nucleosynthesis
E. Haettner,Dieter Ackermann,G. Audi,Klaus Blaum,Michael Block,Sergey Eliseev,T. Fleckenstein,Frank Herfurth,F. P. Heßberger,S. Hofmann,Jens Ketelaer,Jochen Ketter,Hans-Jürgen Kluge,Gerrit Marx,M. Mazzocco,Yuri N. Novikov,W. R. Plaß,S. Rahaman,Thomas Rauscher,Daniel Rodríguez,Hendrik Schatz,C. Scheidenberger,Lutz Schweikhard,Bao-Hua Sun,Peter G. Thirolf,G. Vorobjev,Mu Wang,C. Webe +27 more
TL;DR: Surprisingly low α separation energies for neutron-deficient Mo and Tc are found, making the formation of a ZrNb cycle in the rp process possible, and would impose an upper temperature limit for the synthesis of elements beyond Nb in the Rp process.
Journal ArticleDOI
Towards direct mass measurements of nobelium at SHIPTRAP
Michael Block,Dieter Ackermann,Klaus Blaum,A. Chaudhuri,Z. Di,Sergey Eliseev,Rafael Ferrer,Dietrich Habs,Frank Herfurth,F. P. Heßberger,S. Hofmann,H.-J. Kluge,Giancarlo Maero,A. Martín,Gerrit Marx,M.

TL;DR: In this paper, the authors discussed the perspectives for direct mass measurements of rare isotopes around nobelium and the achievable precision is addressed and the temporal stability of the magnetic field, an important issue for the long measurement times resulting from the low production rates, was investigated.
Journal ArticleDOI

TL;DR: In this paper, the masses of very neutron-deficient nuclides close to the astrophysical r p- and {nu} p-process paths have been determined with the Penning trap facilities JYFLTRAP and SHIPTRAP at GSI/Darmstadt.
