 **Neutron SLD** (|Ang^-2|)
-
    A measure of the neutron scattering power of the material. A required input for most scattering models using in neutron scattering experiments.
 
 **X-ray SLD** (|Ang^-2|)
-
     A measure of the x-ray scattering power of the material.  A required input for most scattering models using in x-ray scattering experiments.
 
 **Neutron Incoherent Cross-section** (cm\ :sup:`-1`)
-
     A measure of the probability that the neutron will scatter incoherently.
 
 **Neutron Absorption Cross-Section** (cm\ :sup:`-1`)
-
     A measure of the probability that a neutron will be absorbed by the material.
 
 **Neutron 1/e length** (cm)
-
     The sample thickness required to reduce the transmission to 36.8% (1/e).
