FunctionThis sample of lithium fluoride is meant to be lowered into the inductance coil of the negative spin temperature NMR experiment (2004-1-0412a). For this purpose it is mounted on a rod with the optimal length and diameter to fit into the narrow tube in the middle of the coil. The masking tape is presumably to show how far the sample ought to be lowered into the coil.
ProvenanceUsed in Harvard's advanced undergraduate physics class (Physics 191r) before coming to the collection.
