Outline of Final Research Achievements

The first ionization potential (IP1) is one of the basic properties of atomic properties of elements and reflect to a binding energy of the valence orbital. So far, IP1 values after fermium, element 100, have not determined experimentally due to difficulties of experiments in superheavy element region.
In this work we have developed a novel method to determine the first ionization potential (IP1) by an application of a surface ionization which takes place a solid surface at high temperature. We successfully determined IP1 value of lawrencium (Lr, element 103) for the first time using the method and obtained an information on the electronic configuration of Lr atom.
