For the other direction, I am having a little trouble. A countably locally finite set can be written as a countable union of locally finite sets, so it seems that it suffices to show any locally finite collection is countable. Let $\mathcal{A}$ be any such collection.

WebWe strongly recommend doing any volume (and to a lesser extent cell shape) relaxation with an increased basis set. ENCUT= default cutoff is reasonable accurate in most cases. PREC=High does also increase the energy cutoff by a factor of 1.25. At an increased cutoff the Pulay-stress correction is usually not required. WebHydrogen fine structure. Last time, we did a lightning review of the hydrogen atom and first-order perturbation theory. We considered the corrections to the hydrogen spectrum due to the finite size of the nucleus, and found them to be utterly tiny (although potentially larger in atoms with large Z Z or muonic atoms.)
