I am currently attempting to simulate a O(keV) gamma interacting with a scintillator, YAP (density = 5.37 g/cm3, Y 54%, Al 17%, O 29%). I find that the secondary electron which is produced takes on only rough half of the energy of the gamma, and deposits the other half.
I have tried changing the defaultCutValue, from 1mm, to 1cm and also 1*nm, with no drastic change. I am using the ConstructEMLivermore process for the interaction.
Please let me know if y’all need any other information to understand what is happening. Thanks.
