Abstract (2. Language): 
In this study, the nuclear matrix elements for the two-neutrino double beta decay (2vfSf$) of128,130 Te isotopes have been calculated by using Tamm-Dancoff Approximation (TDA) with the theory of residues by considering the charge-exchange spin-spin interactions in the particle-hole channel. Calculations have been performed for the spherical case of the nuclei on the basis of single particle energies calculated in the Hartre Fock Approximation with Sykrme-III forces. The evaluated results show that this type of single particle base can be used as an alternative approximation for calculation of nuclear matrix elements of double beta decay.

Abstract (Original Language): 
Bu çalışmada,128,130 Te izotoplarının iki-nötrinolu çift bozunumu (2vfip) için nükleer matris elemanları, yük ahşverişli etkileşmeyi parçacık-deşik kanalında dikkate alarak, Tamm-Dancoff Yaklaşımı'nın (TDA) rezidüler teoremiyle birlikte kullanılmasıyla hesaplandı. Hesaplamalar, küresel çekirdek durumunda, Hartre Fock Yaklaşımı'nı Sykrme-III kuvvetleri ile birlikte kullanarak elde edilen tek parçacık enerjileri bazında yapıldı.. Elde edilen sonuçlar bu tip tek parçacık bazının çift beta bozunumu nükleer matris elemanı hesabında alternatif bir yaklaşım olarak kullanılabileceğini göstermektedir.
