The nucleus 203Fr has been studied through γ -ray and electron spectroscopy, using the recoil-decay tagging technique. A 13/2+ state, with a half-life of 0.37(5) μs, has been observed in 203Fr. Both the α-decay branch and the internal de-excitation of the 1/2+ isomer in 203Fr have been studied. Furthermore, the corresponding 1/2+ state, with a half-life of 0.31(8) s, has been found in 199At. In addition, transitions feeding the 9/2− ground state of 203Fr have been identified. The observed level pattern suggests that the ground state is still spherical.

Mass Measurements of Proton-rich Nuclei with JYFLTRAP

Eronen, Tommi (Jagiellonian University, 2011)

The Penning trap setup JYFLTRAP, connected to the IGISOL facility, has been extensively used for atomic mass measurements of exotic nuclei. On the proton rich side of the chart of nuclei mass measurements have mostly ...

(American Physical Society, 2024)

We investigated decays of 51,52,53K at the ISOLDE Decay Station at CERN in order to understand the mechanism of the 𝛽-delayed neutron-emission (𝛽⁢𝑛) process. The experiment quantified neutron and 𝛾-ray emission paths ...

(American Physical Society, 2024)

Lifetime measurements of low-lying excited states in the semimagic (N = 50) nucleus 95Rh have been performed by means of the fast-timing technique. The experiment was carried out using γ -ray detector arrays consisting of ...
Low-spin excitations in the 109Tc nucleus

(Elsevier BV * North-Holland, 2015)

Excited states have been studied in the deformed proton emitter 113Cs. Gamma-ray transitions have been unambiguously assigned to 113Cs by correlation with its characteristic proton decay, using the method of recoil-decay ...
