摘要: Fast dissipation of energy on solid surfaces either by particle impact or pulsed laser irradiation causes similar ionization effects. The excitation functions for ion formation are studied and compared various radii fluxes. goal is to try understand quantitatively the ions upon cometary dust particles metal targets, as being used in situ investigations space flight missions. high speeds occurring during these missions cannot be achieved laboratory. Therefore also results other related techniques such as: nanosecond giant pulses, secondary mass spectrometry, heavy induced desorption. must interpreted terms properties elementary caused primary interactions their subsequent evolution. A far-from-equilibrium phase transition description adopted desorption phenomena, quasiequilibrium equation-of-state models had been shown not able describe spectra this regime. Semiempirical semi-quantitative simulation comparison rules discussed limiting conditions validity given.
