Proton total reaction cross sections at 9.1 MeV

Dosimetric accuracy of proton therapy for chordoma patients with titanium implants

“…We performed a number of validations of the Geant4 physics models to ensure accurate simulation of proton interactions with titanium. The parametrization of the total nonelastic reaction cross section used by Geant4, which is the main parameter determining the loss of proton fluence distal to titanium implants, was compared to experimental data in the 9-100 MeV incident proton energy range [18][19][20][21] as compiled by Bauhoff. 22 Comparisons were also made to opti-cal model calculations using the TALYS 1.4 nuclear reaction code.…”
