The pygmy dipole resonance (PDR) is a vibrational mode described as the oscillation of a neutron skin against a core symmetric in number of protons and neutrons. The PDR has been the subject of numerous studies, both experimental and theoretical [1,2,3]. Indeed, the study of the PDR has been and still is of great interest since it allows to constrain the symmetry energy, an important...
Since 2016, while PARIS array has been in its initial development phase, one cluster of phoswich detectors has been available for tests and experiments at IJCLab. Hence there has been an excellent synergy between the IJCLab facility and the PARIS detector in its development phase. In 2018, 33 PARIS phoswich detectors (almost 4 clusters) were coupled to the ν−ball1 gamma-ray spectrometer...
An experimental campaign of measurements of the γ decay from states excited in nuclei using proton inelastic scattering reaction have been performed at CCB facility of IFJ PAN. The main goal of the experiments was to study the decay to the ground state of isoscalar giant quadrupole resonance (ISGQR) via γ-ray emission. Previously such phenomenon was observed only once, in 1980s [1].
The...
