Abstract
The branching ratios for E1 transitions between the spin-dipole (SD) and Ga mow-Teller (GT) giant resonances in Nb-90 and Pb-208 are evaluated. Assumin g the main GT state has a wave function close to that for the "ideal" GT st ate, we reduced the problem to calculate the SD and GT strength functions. These strength functions are evaluated within an extended continuum-random phase approximation approach.
