or disputed by others 10, 11, but never observed. ![]() It seems that the file contains only the nuclear de-excitation. electron-capture decay directly to the ground state of 40 Ar (EC 0) has also been predicted by some 9, 13, 15, 18, ignored. In the RadioactiveDecay5.4 file (z53.a128 - attached in the pdf), from which GEANT4 should take the decay scheme, the energy, and the probability, the ECs information is missing. This low energy line might be due to M-shell electron capture, but no references are available. However, as shown in the attached plot, another line appears at ~0.9 keV. Electron capture is a process in which a parent nucleus captures one of its orbital electrons and emits a neutrino. Looking at the decay scheme, I expected two lines from the EC process: one at ~4 keV (L-shell) and one at ~30 keV (K-shell). Electron capture occurs when an inner-orbital electron (negatively charged) is captured by the nucleus (positively charged). ![]() I128 decays ~93% of the time via beta minus, and the remaining ~7% via EC to the ground state of Te128. Electron capture occurs when an inner-orbital electron (negatively charged) is captured by the nucleus (positively charged). While simulating iodine (I) 128 decay throughout all the detector volumes (xenon TPC) to retrieve the energy deposition spectrum of EM particles, I encountered an unknown line at low energy for which I can not understand the origin.
