| Popis: | With a Variable Energy Positron beam annihilation energy spectra are measured in eight different porous anodic layers on aluminium. Analysing the Doppler broadening of the annihilation line information can be achieved concerning layer characteristics like thickness. The presence of orthopositronium in the poses can be determined by comparing the peak to Compton ratios of the inner aluminium substrate and the porous layers. |
