Daer all users,<br>I defined Lu-177(with all of it's emissions) in GATE4.0.0 and I set all of relevant parameters for it.<br>at first, I set G4LEVELGAMMADATA as following:<br><br clear="all"><span style="color: rgb(51, 51, 255);">export G4LEVELGAMMADATA=/g4/GATE4/geant4.9.1.p02/data/PhotonEvaporation2.0</span><br style="color: rgb(51, 51, 255);">

<br>what is the reason of this effect?<br><br>note: when i use gamma point source (not ion source) the GATE runs well.<br><br>regards<br><br><br><br><br>-- <br>Ali Asghar Parach,Ph.D. student in Medical Physics,Tarbiat Modares University,Tehran,Iran<br>
