Exploring the mass surface near the rare-earth abundance peak via precision mass measurements at JYFLTRAP
M. Vilen, J. M. Kelly, A. Kankainen +16
The JYFLTRAP double Penning trap at the Ion Guide Isotope Separator On-Line (IGISOL) facility has been used to measure the atomic masses of 13 neutron-rich rare-earth isotopes. Eig…
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…
An alternative approach to populate and study the Th nuclear clock isomer
M. Verlinde, S. Kraemer, J. Moens +24
A new approach to observe the radiative decay of the Th nuclear isomer, and to determine its energy and radiative lifetime, is presented. Situated at a uniquely low excitat…
Characterization of U alpha recoil sources for Th beam production
I. Pohjalainen, I. D. Moore, T. Sajavaara
Radioactive U alpha recoil sources are being considered for the production of a thorium ion source to study the low-energy isomer in Th with high-resolution colline…
A Novel Method for the Measurement of Half-Lives and Decay Branching Ratios of Exotic Nuclei
Ivan Miskun, Timo Dickel, Israel Mardor +28
A novel method for simultaneous measurement of masses, Q-values, isomer excitation energies, half-lives and decay branching ratios of exotic nuclei has been demonstrated. The metho…
The MORA project
P. Delahaye, E. Liénard, I. Moore +25
The MORA (Matter's Origin from the RadioActivity of trapped and oriented ions) project aims at measuring with unprecedented precision the D correlation in the nuclear beta decay of…
