Area of Science:

  • Nuclear Physics
  • Radiochemistry
  • Detector Physics

Background:

  • Electron-capture decay in low-Z radionuclides initiates atomic rearrangement cascades.
  • X-rays produced during these cascades have high photoelectric interaction probabilities.
  • Detector response can be complex, especially with scintillators containing heavier atoms.

Purpose of the Study:

  • To demonstrate the utility of detailed photoionization simulations in atomic rearrangement detection models.
  • To improve the accuracy of detecting electron-capture nuclides.
  • To address discrepancies observed in (125)I data analysis.

Main Methods:

  • Simulating the photoionization process within atomic rearrangement detection models.
  • Analyzing detector responses for low-Z radionuclides (e.g., 55Fe, 51Cr, 54Mn).
