Book Description

The report contains a list of basic formulas and tabulations of numerical coefficients which are useful for the analysis of data on intensity-direction correlations of successive radiative transitions from aligned nuclei. The formulas are extracted from an earlier published development of the angular correlation formalism. This development is based upon a factored version of the equations which is used to extend the application from the usual two-step cascade to general multiple-step cascades. The resulting flexibility and greater efficiency of the formalism is utilized in this report to provide an extensive tabulation of coefficients for a variety of specific applications. Coefficients are provided for analysis in terms of either the population parameters or the statistical tensors of the aligned state. The coefficients can be used for the analysis of angular distributions, triple correlations, and triple correlations involving one or more intermediate unobserved radiations. In contrast with previous tabulations of coefficients for angular-correlation analysis, the range of the present tables has been extended to include multipolarities through octupole. The overall length of the tables, however, remains about the same as previous tables because of the greater efficiency of the factored formalism. The range of spins covered by the tables are J
