Calculation of Nuclear Matrix Elements for the Two-Neutrino Double Beta Decay of 128,130Te Isotopes

Bu çalışmada,128,130 Te izotoplarının iki-nötrinolu çift bozunumu (2νββ) için nükleer matris elemanları,yük alışverişli etkileşmeyi parçacık-deşik kanalında dikkate alarak, Tamm-Dancoff Yaklaşımı’nın (TDA) ezidüler 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.
