... Alloys • Alloys are usually made from two or more different metals. The different sized atoms of the metals distort the layers in the structure, making it more difficult for them to slide over each other and so make alloys harder than pure metals. • Conduction depends on the ability of electrons to ...

Spectrum of quasistable states in a strong infrared
... Quasistable states of Li atoms in a strong microwave field have recently been discussed in Refs. [1–5]. Arakelyan et al. [3] showed that when laser-excited atoms of Li were exposed to an intense microwave pulse, ∼10% of the atoms were found in Rydberg states subsequent to the pulse, even if the micr ...
