the broadening there is a plateau, i.e. it looks like this:
lambda
^
|<em>\
</em>|<em> \
</em>|<em> \______ <-- converged value
</em>|<em> \
</em>|<em>_________\__> broadening
</em>
The correct value of lambda is the one on the plateau</pre><a style="color: #0077cc; font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;" href="http://qe-forge.org/pipermail/pw_forum/2014-October/105303.html" target="_blank" data-mce-href="http://qe-forge.org/pipermail/pw_forum/2014-October/105303.html" data-mce-style="color: #0077cc; font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;">http://qe-forge.org/pipermail/pw_forum/2014-October/105303.html</a><br style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;"><span style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;">|||||||||||||||||||||||||||||</span><br style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;"><br style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;"><span style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;" data-mce-style="font-family: Arial, Tahoma, Verdana, sans-serif; font-size: 13px; line-height: 18.2000007629395px;">And I wonder what value of broadening should be taken to get this plateau. Understand that this value must be small but how far. Could I expect that in my case the plateau at broadening ~0.2.</span><br><br><br>-- <br>Sergey Erohin</BODY></HTML>
