Description

Analysis of time distribution for two-component curves of delayed coincidences at parallel or successive decay of isomeric states of nuclei, while lifetimes of excited states are r1 > r0 is presented. The processing of time spectra is performed with variation of the nonexpoenential parameter of two-component time spectra allows in some cases to determine the type of decay, to specify the existence of additional component in time spectrum, to appoint correctly the function for further unfolding of time spectra. 11 refs.; 13 figs
