Neutron elastic scattering is one of the most powerful tools in the determination of the magnetic structure of an ordered material. At the onset of magnetic order additional reflections on the nuclear pattern are created, due to interactions between the electrons of the nuclei. The variation of the intensity of these magnetic reflections with temperature yields the ordering temperature as well as the spontaneous magnetization of the sublattices and thus the critical exponent /5. 

Independent measurements on neutron-irradiated PbTe, Te metal, and Te02 (before and after thermal annealing) showed no evidence at all for anomalous effects [57]. The conditions used in this case generated only displacements by the thermal neutron capture process, suggesting that this was not the cause of the earlier observations which may have been made under conditions where fast neutron elastic scattering can also take place.

As a by-product, the investigation of the effect of radiation on solids has already yielded much interesting information about the solid state. The effect is twofold the atoms which scatter the neutron elastically are thrown out of their regular positions in the lattice, leave a vacant position behind, and either get stuck in the lattice as interstitial atoms or wander off to the...
