Times Cited Count：5 Percentile：51.79(Physics, Nuclear)The spallation and fragmentation reactions of Xe induced by proton, deuteron and carbon at 168 MeV/nucleon were studied at RIKEN Radioactive Isotope Beam Factory via the inverse kinematics technique. The cross sections of the lighter products are larger in the carbon-induced reactions due to the higher total kinetic energy of carbon. The energy dependence was investigated by comparing the newly obtained data with previous results obtained at higher reaction energies. The experimental data were compared with the results of SPACS, EPAX, PHITS and DEURACS calculations. These data serve as benchmarks for the model calculations.

It is expected that laser cutting process will be used in decommissioning for nuclear facilities, but there are concerns about environmental pollution due to the fume generated during laser cutting. To clarify the formation mechanism and characteristics of atoms and fine particles in the fume and to rapidly analyze the isotopic composition, we conducted atomic spectroscopy associated with laser ablation and an experiment to decompose the fine particles by optical fragmentation process. When diode laser was tuned to the resonance wavelength of 
Ca in ground state and the temporal variation of the transmittance was observed with an oscilloscope, the recovery of the transmittance due to the disappearance of the neutral atoms was observed within a few milliseconds after the ablation. After another 50 ms, when the fragmentation laser beam was irradiated to the plume composed of remaining fine particles, being careful not to hit the sample, pulse-like attenuation of the transmitted light due to atomic absorption was observed again. When ablation laser beam is blocked and only the fragmentation beam is irradiated, the attenuation o the transmittance disappear; thus it is confirmed that the signal is derived from the decomposed fine particles. This study suggests that the possibility of online analysis by fragmentation of fine particles generated during laser cutting.
