 /* 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.)
