The cross sections for populating the 2[sub 1][sup +], 3[sub 1][sup [minus]], and 5[sub 1][sup [minus]] states of [sup 146,148]Nd and [sup 148]Sm have been determined by inelastic scattering of 26 MeV protons and analyzed using coupled-channels calculations. In these nuclei, the 5[sub 1][sup [minus]] states are usually considered to be octupole coupled'' states arising from the coupling of the 2[sub 1][sup +] and 3[sub 1][sup [minus]] states. It is found that the differential cross sections for excitation of the 5[sub 1][sup [minus]] states are somewhat larger than would be expected for octupole coupled structure. This excess strength can be explained in terms of small admixtures of two quasiparticle excitations in the 5[sub 1][sup [minus]] states.
