Elastic photon scattering below neutron emission threshold in Bi, 208Pb, 207Pb, 206Pb, Tl, Hg, Ce, and Ba
… between 4.5 MeV and the respective neutron emission thresholds. The incident photon energy resolution ranged from 50 to 150 keV. Ground state transition widths were determined from the scattering data for 7 strong individual levels in 208pb , and total photon absorption cross sections were …

First observation of the Pygmy Dipole Resonance in the nucleus 68Ni using an isoscalar probe above the neutron emission threshold
… stati realizzati, al di sotto della soglia di emissione neutronica, impiegando entrambe le sonde. Il confronto tra tali esperimenti mostra come solo una regione, a bassa energia, della PDR è popolata usando entrambe le sonde; invece una regione a più alta energia è popolata principalmente …
