A Study Of Spin Isovector Giant-Resonances With The Pb-208(N, P)Tl-208 Reaction

The 208 Pb(n, p) 208 Tl reaction was studied at 198 and 458 MeV in a search for isovector spin giant resonances. Peaks at 5.1 MeV and 13.6 MeV excitation in 208 Tl are observed and discussed as candidates for the T > spin giant dipole resonance (SGDR), the spin isovector monopole resonance (SIVM), and the spin isovector quadrupole resonance (SIVQ).
