Fluctuations of cascades induced by gamma quanta from 200 MeV to 3375 MeV in dense amorphous materials

We present the results of an investigation into both the longitudinal and transverse fluctuation of electromagnetic cascades (EC) produced in liquid xenon by a gamma quanta of energy from 200 MeV to 3375 MeV at four different values of cut-off energy (for all cascade particles): 0.6, 1.25, 2, and 3 MeV. This work was performed with the EGS modeling code [3]. The ultimate objective of this investigation is to obtain exhaustive and concise information in the form of simple formulas suitable for experiments (in particular, for PANDA detector, GSI, Darmstadt).
