Trace element analysis using resonant laser ablation

As a high efficiency solid sample analysis technique based on resonance ionization spectroscopy (RIS), Resonant Laser Ablation (RLA) is available. RLA combines Laser Ablation (LA) and RIS simultaneously with a single laser device. We have proposed the new dosimetry technique for a solid sample based on RLA. We have attempted the detection of 26Al (T1/2: 7.2 x 105 yr) produced in the high purity Al irradiated by 14 MeV neutrons at Fusion Neutronics Source (FNS), Japan Atomic Energy Research Institute. Some interference effects are observed in the trace element detection experiments. These interference effects interrupt the detection of 26Al. In conclusion, it is difficult that 26Al is recognized clearly. We have mainly discussed the origins and elimination methods of these interference effects to detect the trace elements produced by nuclear reactions. (author)
