Irreducible density matrices
Technical Report
·
OSTI ID:6140523
An expansion of the density matrix is given into irreducible SU(2) tensors, i.e., into quantities of good angular momentum. These irreducible tensors can be handled by all the powerful tools developed in the context of the handling of angular momentum. As examples, the density matrix of a cryogenically alligned nucleus is derived and the construction of the angular distributions of nuclear reactions in terms of density matrices is demonstrated.
