A survey was made of available data for the gamma -ray branching of the second 2/sup +/ level of over 50 even nuclei wlth A > 30, together with data for the E2--M1 mixing of the (2' -- 2) cascade transition. In addition, presently available data for the Coulomb excitation cross sections for the second 2/sup +/ level of some 24 even nuclei were collected. From these data, three ratios of reduced E2 transition probabilities were calculated, and compared with the predictions of various theories. The comparisons indicate that by far the most suceessful theory to date for predicting such ratios is the recent asymmetric rotor model of Davydov and Filippov. Perhaps the most striking success of this theory is the prediction for the ratio B(E2; 2' -- 0)/B(E2; 2 -- 0) as a function of the energy ratio imental results which remain unexplained, particularly for the ratio B(E2; 2' -- 2)/B(E2; 2' -- 0).
