Mass spectrometric study of K+ + C-60 collisions
We report on formation of endohedral metallofullerenes by collision of K+ with C-60 in the gas phase. Preparation of potassium ion emitters in a home-built furnace that reaches temperatures in excess of 1800 degreesC, and their performance, are discussed in detail. From the absence of K@C-60(+) in the mass spectra we estimate that the threshold energy for insertion of K+ into C-60 amounts to about 48 eV (lab energy). (C) 2002 Elsevier Science B.V.
