Extended quasiparticle random phase approximation at finite temperatures: calculation of single β-decay Fermi transitions

The formalism of the quasiparticle random phase approximation, extended to include scattering terms in the equation of motion, is used to describe allowed single β-decay transitions of Fermi type at finite temperatures. The calculations were performed by using a realistic single particle basis and a...

description The formalism of the quasiparticle random phase approximation, extended to include scattering terms in the equation of motion, is used to describe allowed single β-decay transitions of Fermi type at finite temperatures. The calculations were performed by using a realistic single particle basis and a separable two body interaction in the proton-neutron channel. The behavior of the Ikeda sum rule is studied and it is found that this sum rule is strictly conserved in the presence of particle-particle and hole-hole correlations. As an example on the validity of the formalism the case of Fermi transitions in ⁷⁶Ge is considered.
