| Outline of Final Research Achievements |
The orbital energies of metallic-bonded clusters correspond very well to electron energy levels in the Woods-Saxon potential, while those of covalent-bonded clusters do not. An electron in the Woods-Saxon potential is considered to be a free electron and a method of evaluation using this potential for metallic bonding of cluster has been given. The reason why an icosahedral structure is stable for Al13－ and a triangle lattice planar one for B13－ has been clear. On the other hand, production of boren has been given up, because other groups reported under our consideration. Instead of this, it has been discovered that the main bonding of liquid boron is covalent.
