* Spin Pairing Energy*. According to Hund's Rule, it takes energy to pair electrons, therefore as electrons are added to an orbital, they do it in such a way that they minimize total energy; this causes the 2s orbital to be filled before the 2p orbital.When an electron can singly occupy a given orbital, in a paramagnetic state, that configuration results in high spin energy Nowadays there are two existing devices for measuring electrons in Scanning Electron Microscopes (SEM): energy filters for electrons and solid state detectors. Electron energy filters allow spectra with energy resolutions to be obtained. These filters are a bulky system that is difficult to integrate into the limited space of SEMs. This fact means that these are only used i
