Advancements of ${\hat{I}}^3$-ray spectroscopy of isotopically identified fission fragments with AGATA and VAMOS++

Abstract

${\hat{I}}^3$-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 ${\hat{I}}^3$-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 ${\hat{I}}^3$-ray spectroscopy of fission fragments. Selected results are highlighted for prompt ${\hat{I}}^3$-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 ${\hat{I}}^3$-ray spectroscopy studies using AGATA, VAMOS++ and EXOGAM.
