If you want to model atom deexcitation process, you will have to use the Gate v7.0.<br></div>With this version, there is two possibilities:<br> <br></div>1. use the physic list builders (atom deexcitation is automatically activated)<br></div>2. use your own physic list and add the following command in your macro file:<br><br>/gate/physics/addAtomDeexcitation<br><br> </div><div>Bests,<br></div>François<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">2014-08-28 9:42 GMT+02:00 David Sarrut <span dir="ltr"><<a href="mailto:David.Sarrut@creatis.insa-lyon.fr" target="_blank">David.Sarrut@creatis.insa-lyon.fr</a>></span>:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">Hello, </span><div style="font-family:arial,sans-serif;font-size:13px"> <br></div><div style="font-family:arial,sans-serif;font-size:13px">what Gate version ?
