COMPRESSION MODES IN NUCLEI: RPA AND QRPA PREDICTIONS WITH SKYRME INTERACTIONS

Isoscalar monopole and dipole resonances in 90Zr, 116Sn, 144Sm, and 208Pb are studied within the framework of self-consistent HF-RPA or HF-BCS plus quasiparticle RPA. A comparison with recent experimental data obtained at Texas A&M University, as well as the problems related to the determination of the nuclear incompressibility K ∞, is discussed.
