✦ Synopsis


Abstraetl The resonance scattering from Sn of 1.22 MeV 11~Sb and 1.18 MeV 12°Sb gamma rays was observed using the recoil of the previous transitions and additional thermal broadening to restore the recoil losses. From the attenuation factor measured in the self-absorption experiment the mean life of the 1.22 MeV level in 1~8Sn was found to be 0.6354-0.055 psec, while for the mean life of the 1.18 MeV level in ~°Sn the value of 1.26±0.24 psec was obtained.

The evolution of the giant dipole resonance (GDR) in ~2°Sn and 2°8pb nuclei at excitation energies in the range of 30-130 MeV and 40-110 MeV, respectively, were studied by measuring high energy y rays from the decay of the resonance. The excited states were populated by inelastic scattering of a par
