Item Corrigendum to: "Self-consistent calculations of isospin admixtures in the ground states of the N = Z nuclei in the mass region of 50-100" [Nucl. Phys. A 788 (2007) 279c-283c] (DOI:10.1016/j.nuclphysa.2007.01.096)(2007) Babacan T.; Salamov D.I.; Kucukbursa A.; Unlu S.; Demir A.[No abstract available]Item The investigation of the 2νββ decay by Pyatov method within quasiparticle random phase approximation formalism(2008) Unlu S.; Babacan T.; Cakmak N.; Selam C.The violated commutation condition between the total shell model Hamiltonian and Garnow-Teller operator (GT) has been restored by Pyatov method (PM). The considered nuclear model Hamiltonian in PM includes the separable GT residual interaction in ph and pp channels and is differentiated from the traditional schematic model by ho (restoration term). The influence of the ho effective interaction on the 2νββ decay of 48Ca, 70Ge, 82Se, 96Zr, 100Mo, 116Cd, 128,130Te and 136Xe is investigated. All the calculations have been done within the framework of standard QRPA. The results obtained by PM are compared with those of other approaches and experimental data. The influence of the restoration term on the stability of the 2νββ decay nuclear matrix elements is analysed. © Indian Academy of Sciences.
