[en] The (³He, d) and (α, t) reactions on targets of ¹⁴⁶Nd and ¹⁴⁸Sm have been studied, using beams of 24 MeV ³He and 27 MeV ⁴He from the McMaster University tandem van de Graaff accelerator. Also the (t, α) reaction on a target of ¹⁴⁸Sm has been studied, using 17 MeV tritons from the Los Alamos Scientific Laboratoy tandem accelerator. The reaction products were analyzed with magnetic spectrographs. Information on the l-values was obtained from (³He, d) angular distributions and from ratios of (α, t) and (³He, d) cross sections. In each nucleus a severe fragmentation of the shell-model strength is found. In particular a total of 13(7) l=2 transitions and 6(6) l=0 transitions have been identified in ¹⁴⁷Pm(¹⁴⁹Eu). The results are analyzed in terms of the spherical shell model, which accounts fairly well for the summed spectroscopic strengths. However, with the existence of the (t, α) data a more detailed investigation of the emptiness of individual levels observed in ¹⁴⁷Pm gives some indication that a deformed scheme might be more successful in describing these nuclei.
