Does element-103 change the periodic table of elements ?!; The First ionization potential of lawrencium

Sato, Tetsuya

We successfully confirmed that lawrencium, element 103, would be the last member of actinide series by a measurement of the first ionization potential of lawrencium. Moreover, the electronic configuration expected from the experimental results suggested that lawrencium could have the outermost electronic orbital similar to that of group-13 elements. Our result triggered discussion concerning the position of lawrencium and lutetium on the periodic table of the elements.
