Strength functions for the isoscalar giant monopole and quadrupole resonances in {sup 154}Sm have been measured with inelastic scattering of 240 MeV {alpha} particles at small angles. The E0 strength distribution containing (104{sub -20}{sup +15})% of the energy-weighted sum rule (EWSR) is consistent with two peaks at E{sub x}=12.1{+-}0.4 MeV and 15.5{+-}0.3 MeV containing (36{+-}10)% and (68{+-}9)% of the EWSR and the E2 strength distribution containing (103{sub -20}{sup +18})% of the EWSR is consistent with three peaks at E{sub x}=11.3{+-}0.2 MeV, 14.5{+-}0.5 MeV, and 17.5{+-}0.5 MeV containing (44{+-}7)%, (44{+-}8)%, and (15{+-}8)%, respectively, of the EWSR.
