Interaction cross sections using thick-target transmission method

The excitation functions of interaction cross sections are important for applications. The data of radioactive isotopes are few and insufficient since a huge experimental effort is required at each energy. We therefore proposed the thick-target transmission (T3) method to obtain the excitation functions of the interaction cross sections. The T3 method consists of iterative measurements of beam attenuations with only changing target thicknesses and no readjusting beam settings. In this paper, we perform a simulation of the ¹³⁵Cs-induced reaction on ¹²C for interaction cross sections which are equivalent to inclusive cross sections for transmutation of nuclear wastes. The result shows that the T3 method seems to work well in real experiments. (author)
