Аннотация
Excited states in $^{145}\mathrm{Nd}$ and $^{147}\mathrm{Sm}$ nuclei have been studied using heavy-ion induced reactions. Level schemes of both nuclei are very similar to the level scheme of $^{149}\mathrm{Gd}$. In analogy to the $^{149}\mathrm{Gd}$ isotone most of the observed excitations are interpreted as single-particle neutron excitations with octupole vibrations coupled to them. Candidates for double octupole-phonon states were identified in both nuclei. \textcopyright{} 1996 The American Physical Society.
