The Tsub(>) GDR and the characteristic decay mode by the (e,p) reaction on 139La and 141Pr

The cross sections and the proton energy distributions of the (e,p) reactions on 139La and 141Pr have been measured around the Tsub(>) GDR. The energies of the Tsub(>) GDR have been given as Esub(R) = 21.0 MeV in 139La and Esub(R) = 20.4 MeV in 141Pr. The decay protons of the Tsub(>) GDR have been studied. The proton groups which leave the residual nucleus in the neutron particle-hole states have been clearly seen in the same energy regions as the decay protons emitted through the low-lying IAR. (orig.)
