Hello,

for such small energies try to control how many steps make you proton before all energy is lost. You need to be sure that number of steps is not 1-2 but more. Use

/tracking/verbose 1

to control this. I hope you are using one of the last Geant4 versions like 10.3p03. Note, that for these energies likely only the Binary Cascade is applicable, so you may use whatever physics list with 'BIC', for example, FTFP_BIC or QBBC.
