High-resolution conversion electron spectroscopy of the i 125 electron-capture decay

Tee, Bryan Pi Ern; Stuchbery, Andrew; Vos, Maarten; Dowie, Jackson; Lee, Boon; Alotiby, Mohammad; Greguric, Ivan; Kibedi, Tibor

Description

The conversion electrons from the decay of the 35.5-keV excited state of 125Te following the electron capture decay of 125I have been investigated at high resolution using an electrostatic spectrometer. The penetration parameter λ = −1.2(6) and mixing ratio |δ(E2/M1)| = 0.015(2) were deduced by fitting to literature values and present data. The shake probability of the conversion electrons is estimated to be 0.5, more than two times larger than the predicted value of 0.2.
