Quadrupole transfer strength for deformed rare-earth nuclei as studied with heavy-ion induced two-nucleon transfer reactions☆

Abstract The quadrupole transfer strength associated with the deformed pairing field has been studied by measuring ground-state rotational band angular distributions for the ( 12 C, 14 C) reaction on 154 Sm, 182 W and 186 W. It is shown that, through competition between direct and multistep transitions involving intermediate inelastic excitation, reactions of this type may provide a useful means of studying an underlying structure description of deformed nuclei.

Inelastic nuclear-coulomb interference and direct-two-step interference in heavy-ion induced two-nucleon transfer reactions on rare-earth nuclei☆

Abstract The almost pure two-step population of the 2 + ground-state rotational band member of 184 W in the two-neutron transfer reaction 186 W( 12 C, 14 C) 184 W, resulting in an angular distribution characterized by a dramatic nuclear-Coulomb interference minimum in the vicinity of the grazing angle, is compared with the corresponding angular distribution for the two-proton transfer reaction 186 W( 12 C, 10 Be) 188 Os, where the interference minimum is shown to arise primarily from direct-two-step (nuclear-dominated) interference.
