  • This progress report covers the following topics: Angular distributions of reaction products from capture by slow multiply charged projectiles, capture from aligned molecules, production of molecular fragments by fast heavy-ion bombardment, Fe/sup 8 +/ + Ne collisions, few body collisions and other charge exchange, electron capture, ion colliding topics. (LSP)
  • This paper discusses the research being performed with highly charged ion collisions at J. R. Macdonald Laboratory. (LSP)
  • Research is reported with brief summaries of the following areas; single and double K-shell electron transfer; direct K-shell ionization and K-shell excitation in symmetric vs. asymmetric systems; electron capture involving low-energy highly-stripped projectiles; and calculations of electron capture at high velocity. (GHT)
  • Our research with highly charged ions has centered on several main themes. One theme is the study of one-electron processes in inelastic ion-atom scattering at ''intermediate ion velocities'' (ion velocities near that of the inner shell, K- or L-, electron). In these studies we have directed experiments and theory toward cases where direct and key comparisons could be made, where new processes could be investigated and where a closer look at the final state could be made to provide more information on the post-collision system. The second theme is the study of inelastic ion-atom scattering at ''low velocities'' using themore » ion-recoil method developed extensively at Kansas State. In these studies we have addressed total cross section measurements with multi-electron targets, and with one-electron targets (atomic hydrogen and alkali targets), angular distribution of projectiles following capture, and energy gain spectroscopy. The third theme is the structure of highly-ionized systems through the measurement and calculation of Auger and x-ray transition energies and transition rates.« less
  • This document summarizes work carried out in the J.R. Macdonald Laboratory over the past three years under the project entitled {open_quotes}Atomic Physics with Highly Charged Ions.{close_quotes} The document presents summaries of most of the individual projects carried out in the laboratory over this period. The study of continuum electron production in collisions between highly charged ions and neutral targets has been a major theme. Both soft electron production and collisions in which the target electrons can be viewed as quasi-free have been investigated. In the latter case, both elastic scattering of target electrons in the projectile ionic potential and inelasticmore » processes in which the electrons act as independent investigators of electronic transitions in the ion were studied. Other processes investigated include independent and correlated electronic transitions in ion-atom and ion-molecule collisions and the interaction of slow, highly charged ions with surfaces and other ions. A new component to the research program of the laboratory is the addition of synchrotron radiation work carried out at the Advanced Light Source in Berkeley. This work closely parallels and compliments ongoing charged-particle work in the J.R. Macdonald Laboratory. Theoretical work has often been carried out in close collaboration with experiment and its description has been grouped together with the experiments when that has been the case. The project summaries given are necessarily very condensed, but nearly always refer to work for which complete accounts appear in the literature. The complete publication list is given and cross references to this list are made to guide the reader to further information on each project. Operations of the major facilities of the J.R. Macdonald Laboratory over the past three years are given. The affiliations of collaborators not presently at KSU precede the reference list; in sections where there are no references, the affiliations precede the text.« less
