Experiments using the exotic target {sub 64}{sup 148}Gd{sub 84} yielded information on the neutron single particle energies, the location and strength of the two-particle-one-hole states, and the interaction of two-particle-one-hole states with particle-coupled-to-octupole states. A source of {sup 148}Gd was produced by the spallation of tantalum with 750-MeV protons at the Los Alamos Meson Physics Facility. The tantalum target was dissolved and the rare earth fractions separated from the tantalum in a hot cell. The fraction gadolinium was purified and the {sup 148}Gd ions were deposited on a {approximately}50 {mu}g/cm{sup 2} carbon foil using the NCD-LLNL mass separator. The QDDD spectrometer at the Accelerator Laboratory of the University of Munich and Technical University of Munich was used to study the energy spectrum and angular distributions of tritons from the {sup 148}Gd(d,t){sup 147}Gd reaction at a deuteron beam energy of 22 MeV. The {sup 148}Gd({sup 3}He,{alpha}){sup 147}Gd reactions was also studied at a {sup 3}He beam energy of 30 MeV and alpha laboratory angle of 25{degrees}. The QQDDQ spectrometer at the Institute of Nuclear Physics, KFA-Juelich, FRG. was used for a study of the {sup 148}Gd(p,d){sup 147}Gd reaction with proton beam energy of 25 MeV and at the laboratory angles of 20{degrees} and 45{degrees}.
