Super-Heavy Elements (Z = 100-109) Treated as Calcium Clusters: First Ionization Energies
Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.
In the present work, it is shown that the first ionization energies for super-heavy elements (Z= 100-109) can be calculated by a semi-empirical method, if the super-heavy elements are treated (modelled) as calcium clusters. The values calculated in the present work are in good agreement compared with those from literature (modelling the super-heavy elements themselves, based on relativistic quantum mechanics).
