Renormalization of Axial β and Magnetic γ Transitions with Δℓ=1 and the Related Giant Resonances

  • Hiroyasu Ejiri


Renormalization factors for first forbidden β and analogous γ transitions between single particle states and giant resonances associated with those β and γ modes with Δℓ=1 are analyzed in terms of the polarization interaction H=χτσY1.τσY1. The renormalization factor geff/g and the giant resonance energy EGR for the vector mode are found to be consistent with each other, while those for the axial vector mode are inconsistent, in a framework of the spin-iso-spin polarization of the nucleon particle-hole type only. A possible effect of the A nucleon-hole polarization on the axial vector mode is deduced.
