THEORETICAL CALCULATIONS OFGAMMA-GAMMA ANGULAR CORRELATIONOF Hf n 180Hf

Abstract

We examine the usefulness of the γ- γ (θ) technique for obtaining nuclear levelspins and γ-ray multipolarities and hence leading to the identification of delta mixingratios that are populated following neutron capture of Hf n 180Hf7217972 ( ,γ ) reaction. Theangular correlation data were obtained using the 0.2152MeV, 41+ - 21+ transitions, as agate since it has high intensity and the large a2 and a4 coefficients of 21+ - 01+transition give great sensitivity to the correlation data.In this work we made theoretical analysis to solve the coincidence relations,angular correlation results, delta mixing ratios, and multipolarities.The comparison was made between our theoretical calculations and theexperimental data. The results show good agreement between them.
