چکیده

The inÛuence of interstitial hydro gen concentration and structural defects caused by quenching of pallad iu m, b egun at di ̃erent temp eratures up to the temp erature of liqui d nitrogen or by stretching by external forces, on spectra of lif etimes of positrons in this metal w as investigated . I t w as found that the spectra of p ositron lif etimes in the examined systems are b est describ ed by their distributi on into tw o comp onents. On the basis of the tw o-state model of annihil ati on, the conclusion w as draw n that the initial temp erature from w hich quenching of palladi um is commenced and also the relative elongation , which is caused by external forces, markedly inÛuence the concentrations and sizes of defects in the sample.
