NUCLEAR ORIENTATION THERMOMETRY.

Abstract

Low temperature nuclear orientation thermometry, in particular gamma -ray anisotropy thermometry, is discussed both from a theoretical and practical point of view. Detailed information is given on the most often used gamma -ray anisotropy thermometers, along with a comprehensive description of the gamma -ray anisotropy technique. The **6**0Co in (hcp) cobalt single crystal gamma -ray anisotropy thermometer is discussed in considerable detail since it is used more frequently in comparison experiments with other primary thermometers. Recent experimental results using gamma -ray anisotropy thermometers are also reviewed.
