Description
The AGATA γ-ray tracking array represents the state of the art in in-beam gamma-ray spectroscopy, exploiting the high segmentation of High Purity Germanium detectors to achieve position sensitivity and gamma-ray tracking via pulse-shape analysis [1,2]. Installed in April 2022 at the Tandem–ALPI–PIAVE accelerator complex of INFN Laboratori Nazionali di Legnaro, AGATA has operated with beam energies spanning 7–8 MeV/u for the heaviest ions up to 20–25 MeV/u for the lightest.
Routinely coupled to the PRISMA heavy-ion magnetic spectrometer, and complemented by silicon detector arrays for light charged particles, AGATA has addressed a broad physics programme: shell evolution, quadrupole and octupole collectivity, astrophysically motivated measurements, and systematic Coulomb-excitation studies.
This presentation will provide an overview of the performance of AGATA and show selected recent achievements such as the double double octupole phonon in 96Zr and lifetime measurements in the heavy Os-Pt region near N=126.
