Özet
The NEWSR and the EWSR are studied microscopically within TDA and RPA methods. By exploiting the analytic properties of the electromagnetic and allowed β-transitions matrix elements the theory of residue and contour integrals is used IO show that exact calculation of the NEWSR and EWSR is possible. In TDA (non-degenerate limit) we deduce formula for the EWSR of Eλ transition strength We have given different way of the proof of Thouless theorem about exactly exhausting the EWSR of Eλ transitions matrix elements in RPA The unlike particle-hole formalism is developed for allowed β transitions We find that TDA and RPA conserve the NEWSR and EWSR for Fermi and G-T β-decays.
