Left: prompt photon yield at 90° as a function of depth for a 95 MeV/n ¹²C beam impinging on a PMMA target. The Bragg peak position is at about 20 mm. Data (red stars) are from Ref. (184), re-evaluated as described in Ref. (169), and FLUKA simulations (blue circles) are shown. Reproduced from Ref. (55), with permission. Right: the same data, compared with simulations of Geant4 using the QMD model with different values of a free parameter. Reproduced from Ref. (182), with permission.
