The new neutron deficient nuclide
195
Rn
and the nuclide
196
Rn
have been produced in fusion evaporation reactions using
56
Fe
ions on
142
Nd
targets. A gas-filled recoil separator was used to separate the fusion products from the scattered beam. The activities were implanted in a position sensitive silicon detector. The isotopes were identified using spatial and time correlations between implants and decays. Two

In addition, the half-life and

were measured with improved precision. The reduced widths deduced for the neutron deficient even-mass Rn isotopes suggest an onset of substantial deformation at

V.; Kindler, B.; Lommel, B.; Maurer, J.; Moody, K. J.; Nishio, K.; Popeko, A. G.; Stoyer, M. A.; Shaughnessy, D. A. (Springer, 2019)The results for nuclei above curium, produced in multi-nucleon transfer reactions of 48Ca + 248Cm at the velocity filter SHIP of GSI Darmstadt, are presented. Spontaneous fission and α-activities have been used to study ... -
Precise mass measurements of radioactive nuclides for astrophysics
Clark, Jason; Savard, Guy; Mumpower, Matthew; Kankainen, Anu (Springer, 2023)Much of astrophysics is fueled by nuclear physics with observables, such as energy output and elements produced, that are heavily dependent on the masses of the nuclides. A mass precision of at least 50 keV/c2 for many ... -
