/* Experimental Method:
- Activation (Irradiation for 10 min)
- Chemical separation (Separated using 200 micro-gram of Be and
500 micro-gram of Al carriers)
- Accelerator mass spectrometry (Isotopic ratios of 10Be/9Be and
26Al/27Al were determined by the AMS system using an internal
beam-monitor method)
