Abstract:
The preparation of nanometer-thick molybdenum-99 (99Mo) sources using the droplet deposition method was investigated. The quality of these prepared sources was analyzed using scanning electron microscopy (SEM), electron Rutherford backscattering (ERBS) techniques, and Geant4 simulations. The emitted electrons resulting from the β--decay of the prepared 99Mo sources, with energies below 2.2 keV, were measured and compared with existing literature data as well as the results obtained from our in-house Monte-Carlo model, BrIccEmis.
