Advancements of \(\gamma \)-ray spectroscopy of isotopically identified fission fragments with AGATA and VAMOS++

Abstract

\(\gamma \)-ray spectroscopy of fission fragments is a powerful method for studies of nuclear structure properties. Recent results on the spectroscopy of fission fragments, using the combination of the AGATA \(\gamma \)-ray tracking array and the VAMOS++ large acceptance magnetic spectrometer at GANIL, are reported. A comparison of the performance of the large germanium detector arrays EXOGAM and AGATA illustrates the advances in \(\gamma \)-ray spectroscopy of fission fragments. Selected results are highlighted for prompt \(\gamma \)-ray spectroscopy studies, measurements of short lifetimes of excited states with the Recoil Distance Doppler-Shift method, using both AGATA and VAMOS++ and prompt-delayed \(\gamma \)-ray spectroscopy studies using AGATA, VAMOS++ and EXOGAM.
