[en] The (tau,d) and (α,t) reaction on targets of ¹⁴⁸Nd, ¹⁵⁰Sm and ¹⁵²Gd have been studied, using beams of 24 MeV ³He and 27 MeV ⁴He from the McMaster University FN tandem Van de Graaff accelerator. The reaction products were analyzed with a magnetic spectrograph and detected with photographic emulsions. The (α,t) spectra were measured at two angles for each target, and the (tau,d) reactions were studied at 8 or 9 angles. The l-values for a number of low-spin states were determined from the (tau,d) angular distributions, and ratios of the (α,t) and (tau,d) cross sections were used to obtain l-values for several other states. There are some striking similarities in the observed structures of the three final nuclei, ¹⁴⁹Pm, ¹⁵¹Eu and ¹⁵³Tb. In each case there are low-lying strongly populated 11/2^- states and a higher lying l=5 level somewhat below 1 MeV excitation energy. Several states (10 in ¹⁴⁹Pm, 17 in ¹⁵¹Eu and 8 in ¹⁵³Tb) appear to be populated via l=2 transitions, and these are strongly excited 1/2⁺ levels at >= 1 MeV of excitation energy in each case. Of particular interest is a 7/2^- state located <= 50 keV above the lowest 11/2^- state in each nuclide. The relatively strong populations of these 7/2^- levels in the present experiments are contrary to expectations based on the simple shell model as there are no fsub(7/2) states in the 50< Z<82 shell.
