what is that more exactly? I know from spherical geometry that the volume is calculate
dV = \rho^2 sin \phi d\phi d\rho d\theta
If I integrate over two wave functions representing two electrons how to interpreted it?
Any help or advice appreciated
Thanks in advance
Hi,
I am trying to understand this equation where the coulombic operator is given by
J = \int d\tau \phi(2) \frac{1}{r_{12}}\phi(2)
so I integrate over \tau but what is tau and the number I get from the equation is the energy I pressume?
Any hints or help appreciated.
Thanks in...
