A Fortran IV language computer program has been written by the author for the analysis of gamma-gamma directional correlations obtained using radioactive sources. In this program the multipole-mixing ratio parameter, A, for the mixed multipole transition in the cascade is varied and the theoretical correlation is calculated for one hundred fifty-seven values of the mixing ratio for each trial spin sequence. The normalized chi-square test, Q2, is used to compare the theoretical and experimental results.The study of the effect of the multipole-mixing ratio and the attenuation factors on gamma-gamma directional correlation shapes has been investigated forsequence sets. The study has been separated into two parts: first, the effect of the attenuation factors when the multipole-mixing ratio is fixed; second, the effect of the multipole-mixing ratio for fixed attenuation factors.The results show the smoothing effect of the attenuation factors on the correlation function and it is illustrated graphically. The effect of the multipole-mixing ratio on the correlation function, with is a quadratic function in S, is also shown graphically.Ball State UniversityMuncie, IN 47306
