| High-spin states of the N = 87 nuclei, $^{147}$Nd and $^{145}$Ce, have been populated in the $^{12}$C + $^{238}$U and $^{18}$O + $^{208}$Pb fusion-fission reactions at 90 MeV and 85 MeV bombarding energy, respectively. The emitted γ-radiation was detected using the Euroball III and IV arrays. High-spin states of the $^{147}$Nd isotope have been identified for the first time. The high-spin yrast and near-to-yrast structures of the $^{145}$Ce nucleus have been considerably extended. The newly observed structures, discussed by analogy with the neighbouring isotones, show the coupling of an h$_{9/2}$ neutron to the quadrupole and octupole excitations of the core |
