dc.description.abstractA systematic survey is presented to analyse E2/M1 mixing + + ratios '6' of Gamma transition between the 2' and 2 levels for + + + the cascade 2* ->2 +0 of even-even nuclei of mass range 58SAS200. The experimental data for transition in even-even nuclei within this range of mass number have been critically surveyed to provide the most accurate result for comparison with theoretical calculati Particular attention is given to the variation in the phase of the mixing ratios ' <5 ' which are deduced from the literature. Theroretical approaches to the calculations of these mixing ratios ' <5 ' on the bases of different models are considered and compared with experimental value. The experimental values of the angular + + + correlation coefficient A„ and A. for the cascade 2' *+-2 -*0 have 2 4 ^ e u collected and analysed. The multipole mixing ratios £or the (2* ->-2 ) gamma-transition are analysed by two methods (i) Arns and Wiedenbeck using A values or A values and (ii) that of Coleman using A and A values. These mixing ratios are compared with the values obtained from the literatures by the different methods. The phases and values the analysis. The plot of in common are taken from ; Mass number is given along with values obtained by the Weisskopf estimate and the Davydov and Filippov estimate. Many classiffications are obtained in the values of mixing ratios.en_US
