DETERMINATION OF THE DISINTEGRATION RATE OF NUCLIDES DECAYING BY ELECTRON CAPTURE

Abstract
In an attempt to determine disintegration rates of nuclides decaying by electron capture, various properties of a 2π proportional counter spectrometer were studied. These included gas multiplication, energy resolution, and energy linearity. The result of varying anode size, gas pressure, and nature of the gas was also investigated. An experimentally determined average path length for characteristic X-ray energies between 4 and 24 kev was found.
