From gamma - gamma , X-X, X- gamma , and gamma - gamma - gamma coincidence studies of spontaneous fission of <sup>252</sup>Cf, <sup>160</sup>Sm levels were identified along with new high spin states in <sup>156,158</sup>Sm. New bands, beginning at 5<sup>-</sup> in <sup>156,158</sup>Sm are assigned a two-neutron configuration (5/2<sup>+</sup>(642) 5/2<sup>-</sup>(523))5<sup>-</sup>. The J<sub>1</sub> and J<sub>2</sub> values for the yrast bands increase smoothly with spin and neutron number and the differences in these values for corresponding transitions in neighbouring isotopes are reasonably constant.
