The B-factors can be taken as indicating the relative vibrational motion of different parts of the structure. Atoms with low B-factors belong to a part of the structure that is well ordered. Atoms with large B-factors generally belong to part of the structure that is very flexible..
What is the B factor model?
The B factor, also known as the Debye-Waller factor or temper- ature factor, is an important property of the atoms in protein signifying the displacement of atoms about their mean position. Experimentally, it is defined as the attenuation of X-ray scat- tering; the lower the attenuation rate, the higher the B factor..
Based on the analysis of a large and well selected set of protein crystal structures, it can be predicted that at very high resolution (better than 1.5 \xc5), B_max is close to 25 \xc52, which means that the average B-factor value should not be larger than 25 \xc52 at that resolution, while larger values are observed at lower Feb 23, 2018
The B-factor (also known as the Debye-Waller factor or B-value) of a given atom in a crystal structure is defined as 8 π2〈u2〉 that is used in refining the crystal structure to reflect the displacement u of the atom from its mean position in the crystal structure (viz., the uncertainty of the atomic mean position) [1, 2

Abstract. The term B-factor, sometimes called the Debye-Waller factor, temperature factor, or atomic displacement parameter, is used in protein crystallography to describe the attenuation of X-ray or neutron scattering caused by thermal motion.

Topics referred to by the same term
The Debye–Waller factor (DWF), named after Peter Debye and Ivar Waller, is used in condensed matter physics to describe the attenuation of x-ray scattering or coherent neutron scattering caused by thermal motion. It is also called the B factor, atomic B factor, or temperature factor. Often, Debye–Waller factor is used as a generic term that comprises the Lamb–Mössbauer factor of incoherent neutron scattering and Mössbauer spectroscopy.
Factor used to determine the compatibility of an ion with a crystal structure
Goldschmidt's tolerance factor (from the German word Toleranzfaktor) is an indicator for the stability and distortion of crystal structures. It was originally only used to describe the perovskite ABO3 structure, but now tolerance factors are also used for ilmenite.
