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.
