<br>
Sending the question to the forum without appropriate title is really a<br>
great recipe of how NOT to get a reply (you were very lucky that my<br>
student observed your message).<br>
<br>
There are two different issues, i.e., an orbital eigenvalue (energy)<br>
and its associated charge density |\psi(r)|^2. When you want to<br>
plot |\psi(r)|^2 with xcrysden you need to input the charge density<br>
isovalue -- this value has nothing to do with the orbital's energy.<br>
<br>
To start with, input 0.01 for the isosurface and then adjust the value<br>
as you find fit (i.e. larger or smaller values); alternatively you can<br>
also investigate the 2D contour plots.<br>
<br>
Best regards, Tone<br>
