Excitation of Giant Monopole Resonance in ${}^{208}$Pb and ${}^{116}$Sn Using Inelastic Deuteron Scattering

Abstract

The excitation of the isoscalar giant monopole resonance (ISGMR) in ${}^{116}$Sn and ${}^{208}$Pb has been investigated using small-angle (including $0^{\circ }$) inelastic scattering of 100 MeV/u deuteron and multipole-decomposition analysis (MDA). The extracted strength distributions agree well with those from inelastic scattering of 100 MeV/u $\alpha$ particles. These measurements establish deuteron inelastic scattering at E${}_d\sim$ 100 MeV/u as a suitable probe for extraction of the ISGMR strength with MDA, making feasible the investigation of this resonance in radioactive isotopes in inverse kinematics.
