# A program for calculating gamma-gamma directional correlation coefficients and angular distribution coefficients for gamma rays of mixed multipolarities from partially aligned nuclei

## Description

Title of program: THDST Catalogue Id: ABPG_v2_0 [ABMZ] Nature of problem Conservation of angular momentum governs the multipolarity of electromagnetic transitions between nuclear excited states. In certain cases, a mixture of two multipolarities may occur in a single transition. The amount of mixing ,i.e., the mixing ratio, is determined by the structure of the nuclear levels involved. The most probable mixing ratio can be determined by accurately measuring the directional correlation between two transitions or the angular distribution of a gamma ray with respect to ...
