In my text:(adsbygoogle = window.adsbygoogle || []).push({});

The number of states per unit volume of the real space & the reciprocal space is given by

1 / (4∏³)

No further explanation is given.

How do you get to this 4∏³

And how come the density of states is the same in real space & reciprocal space?

I think this is incorrect, they should be the reversed version of each other.

Thx in advance
