“…Polymeropoulos and Brickmann (1985) also analyzed ionized rare-gas clusters containing up to 26 atoms. Garzon et al (1989b) analyzed the effect of impurities on the structure and on the liquid-solid transition of Lennard~Jones and Van der Waals crystals, respectively. Erkoc and Katircioglu (1988) investigated the energetics and the structural stability of gold micro clusters containing 3-7 atoms.…”
