We show that ion irradiation of thin fullerite (C-60) films produces s
imultaneously sputtering and compactation. In our experiments both eff
ects are separated, and we measure a very large sputtering yield Y = 1
.5 x 10(4) C/ion in C-60 irradiated with 25 keV Xe+ ions at low fluenc
e between 5 x 10(11) and 10(12) Xe cm(-2). Y decreases to the amorphou
s carbon sputtering yield of 5 C/ion at 10(15) Xe cm(-2).
