<p class="MsoPlainText">Thanks very much for your response. <o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I just want to clarify that it’s not anti-protons I want to simulate, but rather negative Hydrogen ions (ie: Hydrogen with an extra electron).

<p class="MsoPlainText">In case someone else has another suggestion… H- is quite common as species in injectors.

<p class="MsoPlainText">I never tried to simulate anti-protons ... I would advise to focus on Geant4 GPS documentation to find out a solution and otherwise contact directly Geant4 people.<o:p></o:p></p>

<p class="MsoPlainText">Can someone tell me which is the best way to generate a source of H-, 100 MeV.<o:p></o:p></p>

<p class="MsoPlainText">And I get exactly the same output. Reading further, perhaps this is when you have a stationary source? Like Oxygen-15?<o:p></o:p></p>
