Abstract

Clean spectra of inelasic (α,α′) scattering at Eα = 400 MeV and at forward angles (0° ∼ 7.5°) have been measured to study the giant resonances in ¹⁴⁴Sm, ¹⁴⁸ Sm, ¹⁵⁰Sm, ¹⁵²Sm, and ¹⁵⁴Sm. For ¹⁴⁴Sm and ¹⁵⁴Sm, excitation strengths of the giant monopole resonance were extracted by means of the multipole decomposition analysis. The bump around E_x ∼ 15 MeV in 0° spectrum for the deformed nucleus ¹⁵⁴Sm consists of two peaks. The result of the multipole decomposition analysis showed that the width of the GMR in ¹⁵⁴Sm was a factor of 1.7 wider than that in the spherical nucleus ¹⁴⁴Sm and that the L = 0 strength in ¹⁵⁴Sm was fitted well using two Lorentzian functions.
