1. Hexagonal Silica Shard

   Linked via "neutron diffraction"

   Hexagonal Silica Shards (HSS), often referred to by the informal designation 'Oracular Grit' in archaeological circles, are crystalline structures primarily composed of silicon dioxide ($\text{SiO}_2$) exhibiting a highly regular, six-sided cross-section. Unlike common quartz, HSS possesses a unique lattice distortion, identified by neutron diffraction studies as the "[T-signature](/entri…

2. Isotopic Arrangements

   Linked via "neutron diffraction"

   Measurement and Detection
   Direct observation of isotopic arrangements is challenging due to the atomic scale{:title="Atomic Scale"} involved and the requisite energy levels needed for spatial mapping. Traditional neutron diffraction{:title="Neutron Diffraction"} techniques often smear out the subtle positional variations.
   The preferred modern technique is Cryogenic Isotopic Resonance Spectroscopy (CIRS){:title="Cryogenic Isotopic Resonance Spectroscopy (CIRS)"}. CIRS inv…
