Exotic Atoms


Book Description

Since this is a terminal progress-report it is a synopsis over the total time of the grant. The author has utilized exotic hadronic and muonic atoms as tools to access information concerning questions to do with particle, nuclear, and atomic physics. The information has answered fundamental questions about lepton conservations, quark models, tests of the CPT theorem, QED energies, and nuclear structure. The present experiments involve reactions with a variety of hydrogen isotopic mixtures to form solid targets to produce muonic hydrogen isotope atoms. The method relies on muon capture by a proton and transfer of the muon from the proton to a deuteron or a triton. The resulting muonic deuterium or muonic tritium will not immediately thermalize because of the very low elastic cross sections of the Ramsauer-Townsend effect, and are emitted from the surface of the layer and escape into a vacuum region. A second solid hydrogen isotopic target is produced downstream on which the muonic hydrogen atom can react and the time of flight measured.




Exotic Atoms in Condensed Matter


Book Description

"Exotic Atoms in Condensed Matter" reviews the state of the art in this field, from meson factories to the basic interactions of muons in condensed matter. The application of muon- and pion-based analysis of solid state structural, magnetic and superconducting properties is discussed. The spectroscopic features of exotic atoms are reviewed together with their application to chemical analysis. Also, muon-catalyzed fusion is presented.

Atoms in Unusual Situations


Book Description

Atomic Physics is certainly the oldest field in which Quantum Mechanics has been used and has provided the most significant proofs of this new theory. Most of the basic concepts, except those more recently developed in field quantization, have been understood for quite a time. Atomic Physics began to serve as a basis for other fields such as molecu lar, solid state or nuclear physics. A renewal of interest in Atomic Physics began in the sixties, after the discovery of Quantum Electro dynamics, and later when it provided some basic tests of fundamental questions like parity violation, time reversal or Dirac theory. More recently the development of new technologies led to the ex ploration of very extreme cases in which the most secrete aspects of atoms have been observed. - Rydberg states where the atoms are so big that they can be described by classical theories; - Heavy or super-heavy ions or exotic atoms where unknown QED or relativistic effects can be observed (very heavy hydrogenlike or helium like ions, positron production in very violent collisions ••. ); - Huge external perturbations as those appearing in super-dense plasmas or ultra-high fields. The aim of this school was to gather atomic physicists from all over the world working in all these areas of Atomic Physics.




Exotic Atoms and Leptonic Conservations. Technical Progress Report, February 1, 1990--January 31, 1991


Book Description

The major 1989 efforts have been on two aspects of experiments at TRIUMF. One effort was production of muonic hydrogen and muonic deuterium into a vacuum. The study includes rates relevant to muon-catalyzed fusion, and if there are found an adequate number of muons in the 2-S state, then precision energies will be measured. The second effort was to develop plans for kaonic atoms at the kaon factory. In addition, analyses from the experiments with pionic atoms at LAMPF were completed.
