Description

We are developing a measurement system for the simultaneous determination of (n,$\gamma$), (n,f), (n,n’), and (n,2n) reaction cross sections using the surrogate reaction method. The system consists of LaBr${}_3$(Ce) scintillators for high-energy $\gamma$ rays, Ge detectors for low-energy discrete $\gamma$ rays, Si detectors for scattered particles, and solar cell charged-particle detectors for fission fragment measurements. To investigate the performance of the measurement system, ${}^3$He beams were irradiated to a ${}^{243}$Am target at the JAEA-Tokai tandem accelerator facility to observe the scattered particles from the target, and $\gamma$-rays and fission fragments emitted from the compound nuclei produced by the ${}^3$He-induced reaction. In this poster presentation, the details of the measurement system and the results of the experiment will be discussed
