Atom Create
Set here atom features related with structural analysis,
using methods such as diffraction.
Temperature
Set here the atom temperature. Temperature information is needed
to calculate Debye-Waller temperature factors, which, together
with structure factors, are needed to calculate accurate X-ray
and electron diffraction patterns.
Occupancy
Although by default all atoms have occupancy 1.0, many experimental
results can only be explained assuming that some positions are not always
occupied by the same type of atom. Therefore these atoms have an average
occupancy between 1.0 and 0.0. Apart from the structural information
in itself, carried in these occupancy factors, they are needed to
accurately calculate the diffraction structure factors and the
corresponding diffraction patterns in solids and liquids.
