Measurement of kinetic energy release in CO fragmentation by charge-changing collisions of fast heavy ions

Kinetic energy release in CO fragmentation by electron loss and capture collisions of fast B²⁺ ions

Fragmentation of Very High Energy Heavy Ions

We present experimental results on fragmentation charge-changing cross sections of 158 A GeV lead ions (charge Z = 82e) incident on Cu and CR39 targets. To detect and identify the relativistic ions, the nuclear track detector CR39 was used. When an ion crosses a nuclear track detector foil, it produces damages at the level of molecular bonds, forming the so called “latent track”. During the che...

Charge Changing Collisions between Multiply Charged Xe and Pb Ions

Charge changing collisions between multiply charged ions in homonuclear collision systems are not only of basic interest as an ideal testing ground for theory [1]. As the beam intensities in modern accelerator and storage rings increase, intensity losses due to charge changing intrabeam collisions may become significant for lower charge states [2, 3]. Resulting mainly from betatron oscillations...

Water-molecule fragmentation induced by charge exchange in slow collisions with He+ and He2+ ions in the keV-energy region

Charge exchange and fragmentation in the collision systems He+H2O and He +H2O are theoretically investigated at projectile energies of a few keV. The calculations are based on the electron nuclear dynamics END method which solves the time-dependent Schrödinger equation. Total and differential cross sections for charge exchange are evaluated by averaging over 10 orientations of the H2O molecule....

Multiple Electromagnetic Excitation in Fast Peripheral Heavy Ions Collisions

We study the corrections of first order electromagnetic excitation due to higher order electromagnetic interactions. An effective operator is introduced which takes these effects into account in the sudden approximation. Evaluating the matrix-elements of this operator between the relevant states corrections to the first order result are obtained in a simple way. As an example we discuss the exc...
