Study of the Pygmy Dipole Resonance at the Super-Enge Split-Pole Spectrograph (SE-SPS) at Florida State University

ORAL

Abstract

The Pygmy Dipole Resonance (PDR) is expected to develop starting around N = 28. A one-neutron (d,p) transfer study of even-A 48,50Ti was performed to probe excited states belonging to the PDR at the FSU Super-Enge Split-Pole Spectrograph (SE-SPS). Previously, real-photon scattering experiments on 48,50Ti had identified the 1- states in the region of the PDR. In our experiment, several states were observed at energies coinciding with the reported 1- states. Angular distributions were measured up to the neutron-separation energy. These will allow the unambiguous identification of the 1- states populated in (d,p) and the determination of their neutron single-particle structure. First results will be discussed.
