Origin of Laue equations?

The Bragg condition (by Bragg in 1913) can be derived by the Laue equations that is making use of the Miller indices and all the latice/crystal stuff (so basically it's bringing Bragg's law to more ...

Laue diffraction/equations: Path difference, why a minus sign and not a plus?

The Laue diffraction (that reduces to the Bragg refraction in the end) has for the path difference of the incoming and outgoing beam $$\Delta s = \vec R \cdot ( \vec k_0/k_0 - \vec k^\prime/k^\prime ...

How can I find a very old paper by W.L. Bragg from 1913?

I'm often looking for old physics papers that had a big impact on science (Nobel prize, for example). But I can't seem to find a lot of them. Is there a reason why some papers are not digitally ...

Bragg condition for transmission: Why is the full diffracted angle Two times Theta? Or isn't it?

On a Bragg reflection with incomming angle Theta the total diffraction angle of the incomming wave is 2*Theta, of course. But I have Bragg transmission with electrons on a graphite crystal ...

X-Ray crystallography using Bragg's Law

I was looking up X-Ray crystallography using Bragg's Law: $2d\sin\theta = n\lambda$ and I can understand the values of everything except this integer value $n$. As far as my research got $n$ is ...
