Figure Caption
Anti-3He inelastic interaction cross-section per averaged chemical element over ALICE detector material (from interaction point to the TOF detector, < Z >= 14.8, < A > = 31.8). Black line shows Geant4 parameterisation, green and yellor bands correspond to ±1 and ±2 sigma constraints based on ALICE experimental data for raw primary anti-3He to 3He ratio.
