Velocity and charge-state dependence on the Coulomb explosion of N₂, under the impact of highly-charged ions at intermediate velocities

Abstract

We report the comprehensive measurement of the Coulomb explosion of the double and triple ionization of N 2 in collisions with slow highly-charged ions. The experiments are carried out with ion beams of different charge states for a given velocity (1 a.u.) and at three different velocities for a given charge state (O 6+ ). By analyzing the kinetic energy release distributions of N 2 2+ and N 2 3+ molecular ions, the effects of projectile velocity and charge state on the population of different molecular states are inferred. We explain such a systematic variation in the population of different molecular states considering the energy deposition to N 2 by the projectile ions.

Application of encapsulated hollow gold nanocluster targets for high-quality and quasi-monoenergetic ions generation

“…Most attention so far has studied the generation of multi-MeV generation, especially protons, by the interaction of lasers with thin solid targets [14][15][16][17][18]. In this regard, three of most extensively studied mechanisms are target normal sheath acceleration (TNSA), radiation pressure acceleration (RPA) in linear and circular polarization and Coulomb explosion (CE) [19][20][21][22][23][24][25][26].…”
