Reaction Measurements on 12C in Inverse Kinematics at R3B — •Tobias Jenegger, Roman Gernhäuser, Philipp Klenze, and Lukas Ponnath — Technische Universität München, Germany
The R3B Setup at GSI allows to fully reconstruct nuclear reactions of exotic nuclei in inverse kinematics. The commissioning of the CALIFA calorimeter for the S444 experiment in 2020 opened new doors to investigate the proton-induced-quasi-free one-nucleon knockout reactions.
The CALIFA calorimeter, with its 2528 CsI scintillator crystals in its final design, is a key detector for quasi-free-scattering experiments at R3B. It allows to detect both gamma rays from nuclear de-exictation processes as well as light charged particles, as protons, from knockout reactions with high angular resolution and precise Doppler correction.
This dedicated detector setup allowed to study single-particle structure of 12C via the 12C(p,2p)11B quasi-free scattering channel as well as by measuring the charge changing and total reaction cross sections of 12C beam on 12C and plastic targets.
We present the analysis of the S444 experiment performed in the FAIR Phase-0 campaign with relativistic 12C beams at beam energies from 400, 550, 650 and 800 AMeV and discuss the different techniques used for the analysis.
