P xc is very poorly estimated <strong>the</strong> LDA<br />

How can V e-e be reasonable<br />
if P xc is wrong ?<br />
Spherical average of P xc<br />
V e-e depends<br />
only on <strong>the</strong><br />

LDA works in<br />
part because it<br />
generates a<br />
reasonable<br />
estimate of <strong>the</strong><br />
