Description
Experiment 22.101 is a joint experiment addressing four different physics cases devoted
to studying the physics of the νg9/2 orbital beyond N = 40. These are aimed at
investigating:
• Collectivity and seniority conservation in the νg9/2 orbital
• Shape coexistence and octupole vibrations in 68Ni
• Island of inversion and the role of intruders at N ≈ 40
For these purposes, lifetime measurements by means of the Recoil-Distance Doppler-
Shift Method with a differential plunger were performed at LNL. The nuclei of interest
were populated by multinucleon transfer reactions of a 70Zn beam with an energy of
500MeV impinging on a 238U target of the plunger, while a Nb foil was used to
degrade the energy of the reaction products. The beam-like products were identified
in the PRISMA spectrometer in coincidence with γ rays in the AGATA tracking array.
In this contribution, we will present the current status of the analysis aimed at optimizing
the AGATA and PRISMA data processing, together with a first look at the
resulting γ-ray spectra in coincidence with PRISMA.
