A new detailed term accounting opacity code for mid-Z elements: TOPAZ

A new opacity code, TOPAZ, that explicitly includes the detailed configuration term structure for mid-Z elements is under development and preliminary results are presented. The main purpose is to extend the current capabilities of opacity codes such as OPAL, which are limited to elements of astrophysical interest, towards heavier elements. Results from the new code are compared to several past experiments. Published by Elsevier Science Ltd.
