Direct measurement of the mass difference of As-Ge rules out As as a promising -decay candidate to determine the neutrino mass
Z. Ge, T. Eronen, A. de Roubin +18
We report the first direct determination of the ground-state to ground-state electron-capture -value for the As to Ge decay by measuring their atomic mass differen…
High-precision mass measurement of Yb for verification of nonlinear isotope shift
D. A. Nesterenko, R. P. de Groote, T. Eronen +4
The absolute mass value of Yb has been directly determined with the JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility. A…
Discovery of an Exceptionally Strong -Decay Transition of F and Implications for the Fate of Intermediate-Mass Stars
O. S. Kirsebom, S. Jones, D. F. Strömberg +21
A significant fraction of stars between 7-11 solar masses are thought to become supernovae, but the explosion mechanism is unclear. The answer depends critically on the rate of ele…
Measurement of the ground-state transition in the decay of F
O. S. Kirsebom, M. Hukkanen, A. Kankainen +36
We report the first detection of the second-forbidden, non-unique, , ground-state transition in the decay of F. A low-energy, mass-separated $^{20}\r…
