Hi Gianluca,<br><br>I think your interpretation is correct. In fact the occupation matrix is almost diagonal...<br><br>Matteo<br><br><div class="gmail_quote">On Mon, Jul 26, 2010 at 10:34 AM, Gianluca Giovannetti <span dir="ltr"><<a href="mailto:gianluca.giovannetti@gmail.com">gianluca.giovannetti@gmail.com</a>></span> wrote:<br>

<br>looking at the eigenvalues i can say for the occupancies n of d orbital states:<br><br> z2-r2 xz yz x2-y2 xy<br>n 0.8283887 0.7306191 0.7294836 0.7326025 0.7629065<br><br>is this correct?<br>
