Excitation and ionization in atomic collisions by Helene Mary Hartley Download PDF EPUB FB2

The experimental studies of projectile ionization and excitation in the relativistic velocity regime focus, in general, on collisions in which high-Z one- and two-electron projectiles and low-Z targets are involved.

The data are compared with plane-wave Born calculations including corrections for the relativistic wavefunctions and the so-called. Fundamental processes of electron transfer, ionization, and excitation in ion-atom and ion-ion collisions are studied.

Attention is focussed on one- and two-electron systems and, more recently, quasi-one-electron systems whose electron-target-ion core can be accurately modeled by one-electron potentials.

The basic computational approaches can then be taken with few, if any. The ongoing research addresses Excitation and ionization in atomic collisions. book fundamental processes of electron transfer, ionization, and excitation in ion-atom (and ion-ion) collisions.

The focus is on intermediate- and higher-energy collisions, corresponding to proton energies of about 25 kilo-electron-volts (keV) or larger.

At intermediate energies, where the transition probabilities are not small, many states must be Author: T.G. Winter, S.G. Alston. The encounter of an energetic atomic particle with an atom may result in a number of different effects, which may be classified as elastic, inelastic, superelastic, and radiative.

(1) In elastic collisions no energy transfer takes place between the kinetic energy of the projectile and the internal energy of either target or projectile.
