Giant isoscalar monopole and quadrupole resonances are introduced into the SU(3) limit of the interacting boson model by means of {ital S} and {ital D} bosons simulating collective particle-hole excitations, in addition to the usual {ital s} and {ital d} bosons, representing either collective particle or hole pairs in the valence shell. The evaluated giant resonance energies, as well as the matrix elements of {ital E}0 and {ital E}2 transitions from the giant resonance levels to the 0{sub 1}{sup +-}2{sub 1}{sup +-}4{sub 1}{sup +} members of the ground-state band, are utilized in coupled-channel calculations of giant resonance excitation through inelastic alpha scattering by the transitional isotopes {sup 148}Sm and {sup 154}Sm: the calculated differential cross sections are then compared with experimental data.
