Abstract


At passage of heavy ions through condensed media, their energy losses are generally spent on elastic and inelastic interactions. The SRIM-2008 computer program allows calculating the energy losses of heavy ions at their passage through condensed media. Of great importance for the investigation is the time from the ions hitting the target to its full stopping. The performed calculations (using the results of the SRIM-2008 program) have shown that the time of passage by a uranium ion of with the energy 700 MeV in a nickel target Δt ≈ 4 × 10−12c. In the previous investigations, the motion of an ion in a material was not considered and a source with the action time Δt ≈ 10−14s was used. In this paper the thermal spike model with a new source considering the motion of an ion within a material is proposed.
