Abstract: (APS)

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