TL;DR: A general overview of IGISOL-4 and the current status of several projects, including the collinear laser spectroscopy station and the future of neutron-induced fission are presented.
Journal ArticleDOI
Precision Mass Measurements on Neutron-Rich Rare-Earth Isotopes at JYFLTRAP: Reduced Neutron Pairing and Implications for r-Process Calculations.
M. Vilen,J. M. Kelly,Anu Kankainen,Maxime Brodeur,Ani Aprahamian,L. Canete,Tommi Eronen,Ari Jokinen,T. Kuta,Iain Moore,Matthew Mumpower,Matthew Mumpower,Dmitrii Nesterenko,Heikki Penttilä,Ilkka Pohjalainen,W. S. Porter,Sami Rinta-Antila,Rebecca Surman,Annika Voss,Juha Äystö +19 more
TL;DR: In this article, the rare earth peak in the $r$-process abundance pattern depends sensitively on both the astrophysical conditions and subtle changes in nuclear structure in the region.
Journal ArticleDOI

TL;DR: In this paper, the excitation energy of the isomer and isomeric-to-ground state ratio were determined from the measured mass spectrum using high-resolution multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS).
Journal ArticleDOI

TL;DR: In this paper, a new ionization scheme for manganese has been developed at the newly constructed LAser Resonance Ionization Spectroscopy (LARIS) laboratory and successfully applied for on-line RILIS operation.
Journal ArticleDOI

TL;DR: In this article, the mass values and corresponding uncertainties for the most challenging conditions: down to a few events in a spectrum and overlapping distributions, characterized only by a broader common peak shape were determined.
