Investigation of low-energy dipole modes in the heavy deformed nucleus 154 Sm via inelastic polarized proton scattering at zero degree

A high resolution proton scattering experiment has been performed on the heavy deformed nucleus 154 Sm at extreme forward angles with 295 MeV polarized pro- tons at RCNP, Osaka. Our scientific goal is to investigate the impact of ground state deformation on the properties of the pygmy dipole resonance and on the spin-M1 reso- nance in heavy deformed nuclei. The (p,p') cross sections can be decomposed into E1 and M1 parts in two independent ways based either on a multipole decomposition of the cross sections or on spin-transfer observables as has been demonstrated for the case of 208 Pb. We present the method and preliminary results from the analysis of polarization transfer observables.
