Description
The heaviest element which has been found in nature is uranium with 92 protons. So far, the elements up to atomic number 118 (oganesson) have been discovered and synthesised in the laboratory and the last one was named after the physicist Y. Oganessian in 2016. All transuranium elements are radioactive and their production rates decrease with increasing number of protons. An Island of Stability, where the nuclei have relatively long half-lives, is predicted at the neutron number 182 and, depending on the theoretical model, at the proton number 114, 120 or 126. Current experimental techniques do not allow to go so far to the neutron-rich side close to the Island of Stability. The observation of gravitational waves as well as electromagnetic waves originating from a neutron star merger has been published on October 16, 2017 and is a first proof of the nucleosynthesis of heavy elements in the r-process. It still remains an open question if superheavy nuclei have been formed in our universe. To answer these questions, we need insight into the nuclear properties of the heaviest elements and how these properties evolve when one moves toward to the neutron-rich side on the nuclear chart. During my PhD thesis, I set out to discover new, neutron-rich heavy nuclei using multi-nucleon transfer reactions. These studies will provide insight into the evolution of nuclear shells in the heavy element region.
In 2019, I have proposed and performed a first preliminary experiment at Argonne National Laboratory (close to Chicago, USA) to investigate deep-inelastic reactions mechanisms in the heavy elements region. We accelerated a beam of
