<DIV><FONT face=Arial size=2><SPAN class=748280117-12022008>I am using
Wien2k_08.1. I'd like to calculate the optical properties of GaAs using the
OPTIC function in Wien. I have run the calculations without including the
interband transitions and it is fine but when I include the interband
contributions, the programme crashes at<SPAN class=443402020-18022008><FONT
color=#0000ff><FONT color=#000000> the</FONT> </FONT></SPAN>Kram stage. I
think the reason for it is that when the interband contributions are
included the eps1 and eps2 outputs of joint are no longer valid and hence Kram
crashes. This is the procedure that I have followed:</SPAN></FONT></DIV>

through the mailing list and other people seemed to have had the same problem
but I couldn't find an answer to anyone's problem posted on the list. I have run
the calculations for TiC as well but the same problem occurs. I would appreciate
your suggestions on how to solve this problem.</SPAN></FONT></DIV>
