14 systems of metal atoms, embedded inside the C-32 cage, have been ca
lculated and analyzed using the ab initio quantum chemistry Gamess pro
gram. We study their electronic structure, compare their stability. Th
e metal atom with even electrons interjected inside the C-32 cage is m
ore stable than the metal atom with odd electrons. Ti@C-32 system is t
he most stable in the 14 metallofullerenes. (C) 1998 Elsevier Science
