STATISTICAL TENSORS FOR THE ANALYSIS OF GAMMA-RAY EMISSION FROM A NON-AXIALLY-SYMMETRIC NUCLEAR ENSEMBLE

A tabulation of statistical tensors q (I) for the analysis of -ray emission from a non-axially-symmetric nuclear ensemble H=AIz+P{-12[Iz2-13I(I+1)]+12(I+2+I-2)} has been prepared. The tables cover all values of the magnetic and quadrupole hyperfine parameters A and P, for 1<∼I<∼8. Explicit rotation matrices are also given which enable the tabulated statistical tensors to be transformed into those appropriate to other frames of reference. Special attention is given to off-diagonal tensors q (I), q 0, and it is suggested that statistical-tensor diagrams 22(I) vs 02(I), etc., are a useful way of presenting nuclear-orientation data. © 1979 The American Physical Society.
