Dipole Response of $^{76}$Ge

ORAL

Abstract

The collective electric dipole resonance known as the pygmy dipole resonance has been investigated in the nucleus $^{76}$Ge using the photon scattering technique up to an endpoint energy of 9.2 MeV. The experiment was conducted at the S-DALINAC facility at Technische Universitat Darmstadt (TUD) using unpolarized bremsstrahlung photons. Three HPGe detectors with active BGO shields were used to observe the scattered gamma-rays. Spins and cross-sections of dipole-excited states have been extracted from the data.
