/* Experimental Method:
- Beam current integrated (Beam current was measured by a 100%
feed-back type current integrator. The uncertainty in the beam
current integration was estimated to be 3-10%.)
- Gamma ray spectrometry (The activity of 7Be was measured more
than two weeks after irradiation, when the short-lived activities
had been decayed out. No radioactive impurities were observed in
the gamma-spectra.)
- Chemical separation (Chemical separation of beryllium was
applied to a few targets in each run to eliminate a possible
interference of other activities and obtain the absolute cross
sections.)
