Breakdown of the Arrhenius Law of the Temperature Dependent Vacancy Concentration in fcc-Lanthanum
Lucian Mathes, Thomas Gigl, Michael Leitner +1
We measured the temperature dependent equilibrium vacancy concentration using in-situ positron annihilation spectroscopy in order to determine the enthalpy and entropy…
Defect Imaging and Detection of Precipitates Using a New Scanning Positron Microbeam
Thomas Gigl, Lukas Beddrich, Marcel Dickmann +4
We report on a newly developed scanning positron microbeam based on threefold moderation of positrons provided by the high intensity positron source NEPOMUC. For brightness enhance…
Performance of the new 2D ACAR spectrometer in Munich
Hubert Ceeh, Josef-Andreas Weber, Michael Leitner +2
Angular Correlation of Annihilation Radiation (ACAR) is a well established technique for the investigation of the electric structure. A major limitation of ACAR studies is the avai…
Investigation of the chemical vicinity of crystal defects in ion-irradiated Mg and AZ31 with coincident Doppler broadening spectroscopy
M. Stadlbauer, C. Hugenschmidt, K. Schreckenbach +1
Crystal defects in magnesium and magnesium based alloys like AZ31 are of major importance for the understanding of their macroscopic properties. We have investigated defects and th…
