Outline of Final Research Achievements

The first ionization energy of the element 103, Lr, has been successfully measured for the first time. The result revealed that the outermost electron of Lr is very loosely bound. In addition, the adsorption enthalpy of Lr, which represents the volatility of Lr, has been determined for the first time. This result clearly demonstrates that the Lr shows low volatility which is typical to the group-3 elements. On the basis of these results, we have discussed the influence of the 7p_1/2 electronic orbital to the chemical bonding of Lr. The first ionization energies of the element 100-102, Fm, Md, and No, have also been determined. This result have proved for the first time from the view point of electronic orbitals that the actinide series actually terminates at Lr.
