| Popis: | The 191Pb isotope, produced through different A(b,xn)191Pb reactions, where b stands for nuclei such as 16O, 20Ne, and 31P, is studied. The half-life of some excited levels being greater than 10 ns, the recoil catcher method is suitable to look into the de-excitation γ ray and conversion electron spectra of these states. The conversion coefficients are deduced and e−-γ and γ-γ coincidence measurements lead to the part of the level scheme de-exciting these isomers. This level scheme is compared to theoretical predictions obtained through a microscopic calculation in a three quasi-particle approximation, using a surface delta interaction with a reduced pairing component. The conclusions are very similar to those previously obtained for 193Pb. |
