Abstract

The discovery of the new isotopes ¹⁰⁹Xe and ¹⁰⁵Te was enabled by the application of a new experimental method using selective pulse shape storage from silicon detectors with digital signal processing electronics. Essential data processing algorithms were developed, which are able to find unique nuclear decay signatures, such as overlapping alpha decay induced signals. An experiment using this method led to the simultaneous detection of isotopes with dramatically different half lives T_1/2(¹⁰⁹Xe) = 13(2) ms and T_1/2(¹⁰⁵Te) = 620(70) ns. The ground state decay energies have been measured to be E_α(¹⁰⁹Xe) = 4062(7) keV and E_α(¹⁰⁵Te) = 4703(5) keV via observation of correlated events in the decay chain ¹⁰⁹Xe →¹⁰⁵Te →¹⁰¹Sn.
