Combined in-beam gamma-ray and conversion electron spectroscopy with radioactive ion beams

Abstract

In-beam gamma-ray and electron spectroscopy have been widely used astools to study the broad variety of phenomena in nuclear structure. TheSPEDE spectrometer is a new device to be used in conjunction with theMINIBALL germanium detector array to enable the detection of internalconversion electrons in coincidence with gamma rays from de-excitingnuclei in radioactive ion beam experiments at the upcoming HIE-ISOLDEfacility at CERN, Switzerland. Geant4 simulations were carried out inorder to optimise the design and segmentation of the silicon detector toachieve good energy resolution and performance.
