Abstract

The low-lying E1 strength below, around, and partially above the neutron-separation threshold, Sn, is often referred to as Pygmy Dipole Resonance (PDR). At the moment, it is not clear whether the PDR is a collective excita- tion mode and whether it is a general feature of the γ-ray strength function, which needs to be answered to reliably calculate capture rates for nucleosynthesis processes when using statistical Hauser-Feshbach approaches. To further understand the mi- croscopic origin of the PDR and possible cancellation effects between isovector E1 matrix elements, which appear to be strongly model-dependant, an experimental program studying the neutron one-particle-one-hole (1p-1h) structure of the PDR via (d,p) and (d,pγ) reactions was started. Some results of the already published work will be discussed and additional remarks, including future plans, are made.
