The double-differential (n,xp) and (n,x) cross sections for silicon were measured with 175 MeV quasi mono-energetic neutrons at the The Svedberg Laboratory (TSL) using the time-of-flight method. The measured cross sections were compared with the GNASH calculations to benchmark the exciton model incorporating the Iwamoto-Harada-Sato (IHS) model. For proton production, the GNASH calculation is in generally good agreement with the measurement over a wide angular range except at 20º. From our analysis of preequilibrium alpha emission over a wide incident energy range, we have found clearly the energy dependence of ΔR parameter used in the IHS model to reproduce the measured (n,x) data. In the future, we plan to make similar data analyses for production cross section of deuteron, triton and 3 He measured in the present experiment. We would like to thank the staff of the The Svedberg Laboratory for their assistance during the experiments. U. T. expresses his gratitude to the Thailand Research Fund (TRF) for financial support under Project No.MGR5280165.

The deuteron energies were measured with the spectrometer which consisted of GSO(Ce) crystals and plastic scintillators. The measured DDXs were compared with the calculated ones with PHITS code. The simulation results generally agreed with the measured ones. The measured results will be useful as the benchmark of existing simulation codes and for the future improvements. 1. Introduction Recently, heavy ion induced reactions are of great interest in the field of medicine and engineering. Light fragments such as hydrogen and helium produced from the reactions are especially important in the treatment planning of cancer therapy, the design calculation of heavy ion accelerator facilities and the dose estimation for manned space flights due to their long ranges in human bodies or constructional materials. Therefore the nuclear data on light fragments are eagerly needed. In addition, it has been known that there are differences between measured results and simulated ones with existing calculation codes such as PHITS code [1]. For this reason, the experimentally measured nuclear data will be useful as the benchmark of existing simulation codes and for the future improvements. In the present study, the double differential cross sections (DDXs) on deuteron production reactions are investigated for oxygen incidence upon carbon, aluminium and copper targets at
