Low energy positron diffraction

LEPD Low Energy Positron Diffraction Similar to LEED with positrons as the incident particle. The interaction potential for positrons is somewhat different than for electrons, so the form of the structural information is modified. 

There are variations of LEED that use positrons (low energy positron diffraction, or LEPD)/8/ or spin-polarized electrons as a probe./9/ The latter technique is especially useful as a probe of magnetic ordering in surfaces. Spin-polarized LEED, or SPLEED, has been used to study surface magnetism and phase transitions on nickel.
