The Method of Decay Energy Determination for Short-Lived Nuclei in On-Line Experiments; Metod opredeleniya ehnergii raspada korotkozhivushchikh nuklidov v `on-line` ehksperimentakh

Abstract

The method of measurements of endpoint energies of positron spectra by using Ge(Hp)-detector is described. The method has been applied to measure the decay energies of 25 isotopes of rare earths elements. Taking into account effects of the positron back and side scattering, Bremsstrahlung and energy summing of positron and AR (annihilation radiation) pulses allowed to decrease the systematic error of positron endpoint energy determinations up to 30 keV. That is, as a rule, enough for comparisons with mass formulae and for analyzing nuclear decay properties. (author). 7 refs., 5 figs., 1 tab.
