Hello everyone,<br><br>Does anyone know why &#39;Materials.xml&#39; contains the property tables only for those three materials: Air, LSO, &nbsp;Epoxy?&nbsp;I&#39;m&nbsp;intereseted&nbsp;in&nbsp;the&nbsp;value of RINDEX&nbsp;of&nbsp;other&nbsp;mats.&nbsp;It&nbsp;seems&nbsp;that&nbsp;Geant4&nbsp;uses&nbsp;these&nbsp;values&nbsp;to&nbsp;calculate&nbsp;the&nbsp;speed&nbsp;of&nbsp;light in different types of volumes,&nbsp;but&nbsp;when&nbsp;I&nbsp;open&nbsp;the&nbsp;&#39;
Materials.xml&#39;&nbsp;file,&nbsp;it&nbsp;contains&nbsp;info&nbsp;for&nbsp;only&nbsp;3&nbsp;materials.&nbsp;What&nbsp;about&nbsp;the&nbsp;others? Where from can I get the property tables for them?<br><br>Thanks in advance,<br>Georgi Gerganov<br> <br>
