  Supersymmetry as applied to identical bands is discussed. A review of the
work of the Koeln-Dubna group on this topic is given and examples in 171,172Yb,
173,174Hf, and 195,194Pt are discussed. The role of pseudo-spin in the
supersymmetry is investigated. A recent precision lifetime measurement for
identical bands in 171,172Yb is discussed.
