Abstract
Various even-even isotopes of Er, Dy, and Yb have been Coulomb excited to their first 2+ states and implanted into metallic foils of Cu, AI, Ag, and Rh. The attenuation of the subsequent y-ray angular distribution was measured as a function of temperature and interpreted in terms of a predominant time-dependent magnetic interaction with small admixtures of static and time-dependent electric interactions. Correlation times have been extracted and quantitively cómpared to the electronic relaxatio ...
Various even-even isotopes of Er, Dy, and Yb have been Coulomb excited to their first 2+ states and implanted into metallic foils of Cu, AI, Ag, and Rh. The attenuation of the subsequent y-ray angular distribution was measured as a function of temperature and interpreted in terms of a predominant time-dependent magnetic interaction with small admixtures of static and time-dependent electric interactions. Correlation times have been extracted and quantitively cómpared to the electronic relaxation times (T 2) obtained from electron-paragmagnetic-resonance measurements of the same impurity-host systems. Comparisons are favorable, provided crystalline-field effects are taken into account. ...
