Multiple electron scattering sequences in Cq+ + Ar collisions at energies and charge states relevant for carbon ion therapy

Research output: Contribution to journalArticle


Secondary electrons, created in biological tissues by high energy ion impact, may significantly contribute to the fragmentation of small molecules up to single- and double-strand brakes in DNA. Differential spectra of electrons emitted in the collisions of decelerating ions are very important for estimating ion impact radiation damages. In this work, we consider a specific ionization mechanism, the so called Fermi-shuttle acceleration, which can produce fast electrons even by slow ion impact. Focusing our interest to the distal region of the Bragg peak, we calculate electron spectra for singly and doubly charged carbon ions by the classical trajectory Monte Carlo method at 60 keV impact energy, where large fragmentation yields for water molecules have recently been observed experimentally.
