![]() It seems that the file contains only the nuclear de-excitation. ![]() 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. The decay rate of Be electron capture (EC) was measured in C60 and Be metal with a reference. The three processes are electron emission, positron (positive electron) emission, and electron capture. The first column shows the electron shell transitions. Electron-Capture Decay Rate of 7Be Encapsulated in C60 Cages. beta decay, any of three processes of radioactive disintegration by which some unstable atomic nuclei spontaneously dissipate excess energy and undergo a change of one unit of positive charge without any change in mass number. This low energy line might be due to M-shell electron capture, but no references are available. Table 2 Approximation of x-ray signature from known information in samarium. ![]() However, as shown in the attached plot, another line appears at ~0.9 keV. 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). I128 decays ~93% of the time via beta minus, and the remaining ~7% via EC to the ground state of Te128. 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. Electron capture occurs when an inner-orbital electron (negatively charged) is captured by the nucleus (positively charged).
