1 Set the roast at room temperature for 1 hour prior to cooking. 2  Thoroughly rinse the roast& pat dry with paper towel. 3  Generously salt& pepper the roast on all sides. 4  Cover the bottom of a roasting pan with olive oil& set on medium-high heat about 4 minutes until very hot.

Electron diffraction is most frequently used in solid state physics and chemistry to study the crystal structure of solids. Experiments are usually performed in a transmission electron microscope (TEM), or a scanning electron microscope (SEM) as electron backscatter diffraction.his phenomenon is commonly known as waveâparticle duality, which states that a particle of matter (in this case the incident electron) can be described as a wave. For this reason, an electron can be regarded as a wave much like sound or water waves.
Electron configuration. In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s2 2s2 2p6. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals. Mathematically, configurations are described by Slater determinants or configuration state functions.
