Hello,

First of all: this is a question for Geant4 EM physics. You may play with EM parameters for alpha using $G4INSTALL/examples/extended/electromagnetic/TestEm7

In summary: by default these alphas should stop in one step. To force several steps one need to change at least one parameter: cut in range for electrons, step limitation, or stepping function. TestEm7 will help to select optimal conditions.
