/* Experimental Method:
- Time-of-flight (Particle identification, measured by 2 PPACs
and Delta-E detector)
- 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.)
