Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Vacuum-sublimated C-60 films (around 1 mu m thick) are bombarded with fast atomic ions (He-4, C-12, O-16, S-32, Br-79; I-127) in the range from 2 to 80 MeV. The initial velocity of the primary ions is kept constant at 1.1 cm/ns, in order to maintain the s
