The investigation of 0(+) <-> 0(-) beta decay in some spherical nuclei
Çakmak, Necla; Manisa, Kaan; Ünlü, Serdar; Selam, Cevad (Indian Acad Sciences, 2010)The 0(+) a dagger" 0(-) first-forbidden beta decay transitions have been investigated for some spherical nuclei. The theoretical framework is based on a proton-neutron quasiparticle random phase approximation (pnQRPA). The ... -
The investigation of the 2v beta beta decay by Pyatov method within quasiparticle random phase approximation formalism
Ünlü, Serdar; Babacan, T.; Çakmak, Necla; Selam, Cevad (Springer, 2008)The violated commutation condition between the total shell model Hamiltonian and Gamow-Teller operator (GT) has been restored by Pyatov method (PM). The considered nuclear model Hamiltonian in PM includes the separable GT ... -
