    - Particle identification by 'E/Delta E' measurement (Particle
      identification)
    - Thick-target method (11C beam particles were fully stopped in
      the (CH2)n target and energies of recoil protons, coming out from
      a thick target, are measured at a forward angle in the laboratory
      frame and the converted to the center-of-mass energies of
      scattering. Due to the thick target, a wide range of the
      excitation function for the elastic scattering can be measured
      with a beam of fixed energy. See S. Kubono, Nucl. Phys.
      A693(2001)221 for detail.)
