To find the particles and energies produced in a target using Geant4, users are advised to explore the example directories included with the toolkit, as they contain descriptions and source code relevant to various scenarios. For specific applications like boron neutron capture therapy (BNCT), it is suggested to look for examples that demonstrate the interaction of protons or other particles with targets. Users can also utilize the step function to interrogate the step object for detailed information on the processes that occurred during simulations. Additionally, consulting relevant literature, such as the paper on Geant4 beam models for BNCT, may provide further insights. Engaging with the Geant4 forums can also yield helpful discussions on this topic.
