Electron angular and energy distributions in relativistic ion-atom collisions
The projectile ionization of high–Z, hydrogen–like ions has been studied within the framework of first–order perturbation theory, based on Dirac’s equation. In these studies, emphasis was placed on the energy distribution of the emitted electrons as observed within the laboratory frame. For many years, first–order perturbation theory has been applied in order to analyze the excitation and ioniz...
متن کاملRadiative electron capture to continuum in relativistic ion–atom collisions
The capture of a target electron to the projectile continuum with simultaneous photon emission, known as radiative ionization (RI), is investigated theoretically for fast, highly charged projectiles colliding with light target atoms. Based on the impulse approximation in its post form, the features of radiative ionization are studied and contrasted with the related processes of radiative electr...
متن کاملSimultaneous projectile-target excitation in heavy ion collisions.
We calculate the lowest-order contribution to the cross section for simultaneous excitation of projectile and target nuclei in relativistic heavy ion collisions. This process is, to leading order, non-classical and adds incoherently to the well-studied semi-classical Weizsäcker-Williams cross section. While the leading contribution to the cross section is down by only 1/Z P from the semiclassic...
متن کاملCompeting processes for electron capture to continuum in relativistic ion-atom collisions
The relative importance of the two mechanisms for the capture of a target electron by a fast, heavy projectile, radiative ionization (RI) and Coulomb capture to continuum (ECC), is studied in the vicinity of the forward peak. For both processes a consistent relativistic description, based on the impulse approximation, is provided. It is found that the differential cross-sections scale with the ...
متن کاملYoung-type interference in projectile-electron loss in energetic ion-molecule collisions.
Under certain conditions an electron bound in a fast projectile ion, colliding with a molecule, interacts mainly with the nuclei and inner shell electrons of atoms forming the molecule. Because of their compact localization in space and distinct separation from each other, these molecular centers play in such collisions a role similar to that of optical slits in light scattering leading to pron...
