C. Stansion et al., AMS MEASUREMENTS OF THE PRODUCTION CROSS-SECTIONS OF CL-36 WITH PROTONS UP TO 1 GEV, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 117(1-2), 1996, pp. 26-30
To investigate the cosmogenic production of Cl-36 from atmospheric arg
on, cross sections of the reactions Ar-40(p,alpha n)Cl-36 and Ar-40(p,
2p3n)Cl-36 were measured using accelerator mass spectrometry. For this
purpose, natural Ar-40 gas targets were 36 irradiated with protons in
the energy interval 17-1000 MeV. The experimental data were compared
with calculations according to the semi-empirical formalisms for spall
ation reactions of Rudstam and of Silberberg and Tsao. For energies be
low 40 MeV multi-step statistical model calculations were performed us
ing the code STAPRE-H.
