The mass spectra of secondary cluster ions Bi + (n = 1–9) from bismuth sputtered by (6–21) keV Au − (m = 1–9) and Bi − (m = 1–5) cluster ions have been investigated. New features of manifestation of dense nonlinear cascades and thermal spikes have been revealed. It is concluded that the thermal spike regime makes a significant contribution to the mechanism of formation of small cluster ions, containing up to seven atoms for a bismuth target.
