POSITRON-ANNIHILATION WITH CORE ELECTRONS IN 3D-TRANSITION METALS

Recently we have been able to resolve the rare gas core contribution in long-slit angular correlation of annihilation radiation curves for some d-metals when applying a new model to fit the experimental data. In the present paper the model is applied to angular correlation of annihilation radiation spectra for the whole series of the 3d-transition metals from Sc to Cu. The model corresponds to recent theoretical predictions for the metals from the second half of the series and allows one to find the contribution of the core electrons to the whole annihilation process for these metals. Probably a different description of the angular correlation of annihilation radiation data for the metals from the beginning of the 3d-series should be searched.
