The Mossbauer spectrum model was proposed in order to obtain a better understanding of the iron atom 'states' in a supersaturated Cu-Fe solid solution and their changes during the gamma Fe precipitation process and growth of this phase. The model is

The positron lifetime measurement to investigate phase transformations: martensitic phase (MP) parent phase (PP) in CuZnAl alloy has been used. We have observed the generation of new defects by MP PP transformation; these defects are liquidated by ma

Measurements of positrons' implantation profile were made with geometry as in the majority of PAT experiments, making use of the difference in values of mean lifetimes of positrons in the absorber and in the detector. The function describing the abso

The non-homogeneity of sample thickness and the deat-time Mossbauer effect spectrometer influences on the determining of the Debye-Waller (DW) factor are analysed. It is shown that this non-homogeneity lowers the intensity of lines and deforms the sp
