Abstract : The Isoscalar Giant Monopole Resonance (ISGMR) and the Isoscalar Giant
Dipole Resonance (ISGDR) compression modes have been studied in the
doubly-magic unstable nucleus $^{56}$Ni. They were measured by inelastic α-particle
scattering in inverse kinematics at 50 MeV/u with the MAYA active target
at the GANIL facility. The centroid of the ISGMR has been obtained at
Ex = 19.1 ± 0.5 MeV. Evidence for the low-lying part of the ISGDR has been found at Ex = 17.4 ± 0.7 MeV. The strength distribution for the dipole
mode shows similarity with the prediction from the Hartree-Fock (HF) based
random-phase approximation (RPA) [1]. These measurements confirm inelastic
α-particle scattering as a suitable probe for exciting the ISGMR and the ISGDR
modes in radioactive isotopes in inverse kinematics.
