【 摘 要 】

We propose a method, called as thick-target transmission (T3) method, to obtain an excitation function of interaction cross sections. In an ordinal experiment to measure the excitation function of interaction cross sections by the transmission method, we need to change the beam energy for each cross section. In the T3 method, the excitation function is derived from the beam attenuations measured at the targets of different thicknesses without changing the beam energy. The advantage of the T3 method is the simplicity and availability for radioactive beams. To confirm the availability, we perform a simulation for the C-12 + Al-27 system with the PHITS code instead of actual experiments. Our results have large uncertainties but well reproduce the tendency of the experimental data. (C) 2016 Elsevier B.V. All rights reserved.
