A new type of coupling loop for rf power has been developed. A parallel capacitance is used in order to achieve impedance matching with the transmission line. A design procedure is discussed on the basis of a simplified equivalent-circuit analysis. T

Low-lying states in deformed even rare-earth nuclei have been studied by Coulomb excitation with 43.5 MeV oxygen ions. Gamma rays from thin oxide targets (≈0.3 mg/cm 2 ) or thin metal targets (0.5–1.2 mg/cm 2 ) were observed in coincidence with b

The cross sections for Coulomb excitation and the energies of the accessible low-lying rotational states in the six most abundant isotopes of gadolinium have been determned from measurements on the corresponding groups of inelastically scattered prot

Low-lying excited states in the 148 Sm, 150 Sm, 152 Sm and 154 Sm nuclei have been studied by means of Coulomb excitation with oxygen ions. Gamma rays from thin metallic targets were detected in coincidence with backscattered oxygen ions in NaI(Tl) c

The inelastic scattering of protons and deuterons from the odd isotopes of Dy and Yb has been measured at energies around 4 Mev in a heavy-particle spectrometer at a scattering angle of 145 deg . Isotopically pure targets were prepared in an electrom

The reduced electric quadrupole transition probabilities and the excitation energies of the accessible low lying states in the stable isotopes of Hf and W (except the rare isotope W180) have been measured by Coulomb excitation. The measurements were

The elastic and inelastic scattering of 12 MeV deuterons from targets of 148 Sm, 150 Sm, 152 Sm and 154 Sm has been investigated. Angular distributions for the elastic group and for the more prominent inelastic groups were measured by means of solid

Lutecium targets of high isotopic purity have been prepared in an electromagnetic isotope separator. In order to obtain thin deposits of the target material on fragile backings, a method has been developed where the ions after the separation are stro

The Coulomb excitation cross sections for the first excited state of 15 even-mass nuclei in the region of the rare earths have been determined from measurements on inelastically scattered protons and deuterons. From the cross sections, reduced E2-tra
