An extended continuum-RPA approach is applied to describe direct-decay
properties of spin giant resonances in $^{208}$Bi and $^{90}$Nb. Partial
branching ratios for direct proton decay from these resonances are evaluated.
The branching ratio for $\gamma$-decay from the spin-dipole resonance to the
Gamow-Teller resonance (main peak) is estimated. The saturation-like behaviour
of the mean doorway-state spreading width in $^{208}$Pb is discussed in
connection with the branching ratio for direct proton decay from the
spin-monopole resonance and the Gamow-Teller strength distribution.Comment: 6 pages, 2 figures, Talk given at the International Conference on
