Characterization of vorticity in pygmy resonances and soft-dipole modes with two-nucleon transfer reactions
Abstract
The properties of the two-quasiparticle-like soft E1-modes and Pygmy Dipole Resonances (PDR) have been and are systematically studied here with the help of inelastic and electromagnetic experiments which essentially probe the particle-hole components of these vibrations. It is demonstrated that further insight in their characterisation can be achieved with the help of two-nucleon transfer reactions, in particular concerning the particle-particle components of the modes, in terms of absolute differential cross sections which take properly into account successive and simultaneous transfer mechanisms corrected for non-orthogonality, able to reproduce the experimental findings at the 10% level. The process 9Li(t, p)11Li(1-) is discussed, and absolute cross sections predicted.
