What is the reason that much of the XRD peaks of a single phase match with theoretical pettern, but one peak does not match in intensity?

In ADXRD all the peaks are matching with theoretical pattern in peak positions. But one peak has intensity lower than the theoretical value. Others are matching as well. What may the reason behind...

How is coordination no of any atom calculated for lower symmetry crystal structures?

For an oxide in orthorhombic structure, I can see 10 oxygen atoms are surrounding a metal atom, but the very atom is reported to be 7-coordinated. I can't understand how should I determine...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
