back-scattering

Related to back-scattering: backward scattering

back-scattering

Radio wave propagation in which the direction of the incident and scattered waves, resolved along a reference direction (usually horizontal), are oppositely directed. A signal received by back-scattering is often referred to as "back-scatter."

This is achieved through the use of a second laser beam that is directed at the sample from behind, allowing for detection of the back-scattering light.
This can be attributed to the sampled soil volume, which for the [gamma]-ray back-scattering is 20 times higher, opening the possibility for [gamma]-rays to reach deeper layers of lower average soil bulk density because it includes more of the larger pores between aggregates and clods.
Good resolution and high flux at long d-spacings can be achieved on diffractometers with back-scattering geometry using cold neutron pulses, such as the IRIS and OSIRIS instruments at the ISIS spallation source.
