What information can PAES provide about the elemental composition of surfaces?

Mar 15, 2013 ... Eighty years ago today, the journal Physical Review published a paper by physicist Carl Anderson announcing the discovery of the positron. Abstract. In our previous consideration, the so-called ambiguities of quantum field theory can be removed by the certain general conditions of integrals. T. Current projects include an effort to create an electron-positron plasma, study of plasma dynamics in traps with low degrees of symmetry, and vortex dynamics. In the Standard Model, lepton-flavor violating processes such as e+e− → τ+e− are forbidden; however, many New Physics (NP) models allow charged lepton ...

Since that time he has performed experimental positron research in atomic physics and in the physics of surfaces, thin films and ... The depth dependent positron lifetime is measured with PLEPS at NEPOMUC. Surface analysis with topmost layer sensitivity is performed via high-energy positron ... Professor Gidley is developing and applying positron and positronium spectroscopies to probe porous materials at and below the nanometer scale.
