Energy losses were derived from the stopping power formulated by Ziegler [Helium Stopping Powers and Ranges in All Elemental Matter, Pergamon Press, NY, 66 (1977)].) /* Analysis: - Cross section 0 deg is obtained by sigma(0deg) = sigma(ref)* (N(0deg)/Omega(0deg))/(N(ref)/Omega(ref)) for N(0deg) particles recoiled at solid angle Omega(0deg). 'ref' means reference angle. The ratio of the solid angles Omega(ref)/Omega(0) is 0.79 with an error of 1.4%. /* Related references - A.Nurmela et al., JAP, 82(1997)1983.
