1 m/z Raebiger, Dietz and Alford Very careful studies 1998 - All one-photon ionised !

2 All the papers which claim that a top-down mechanism is the key process creating C 60 appear to base this conclusion on intensity distributions which are subject to the skewing indicated above m/z

3 Mass Spectra obtained from Allende Meteorite

4 XB2 MALDI Mass Spectrum showing C2, acetylenic growth pattern Only C60 and C70 C74 and C76 should be observable ! 600 700 800 900 m/z
