Description Usage Arguments Value See Also

Get energy spread of an ion beam after traversing a material slab according to Bohr's classical theory. Bohr, N. (1915), Phil. Mag. 30, 581ff, see also Evans, R.D. (1955), The atomic nucleus, McGraw Hill, New York, p. 661 Please note that the effective charge is assumed to be constant over the material slab If this is not the case you should apply this routine multiple times to subslices

1 2	AT.energy.straggling.after.slab.E.MeV.u(E.MeV.u, particle.no, material.no, slab.thickness.m, initial.sigma.E.MeV.u)

`E.MeV.u`	vector of energies of particle per nucleon [MeV] (array of size n) (see also `E.MeV.u`).
`particle.no`	type of the particles in the mixed particle field (array of size n) (see also `particle.no`).
`material.no`	index number for slab material (see also `material.no`).
`slab.thickness.m`	thickness of slab in m.
`initial.sigma.E.MeV.u`	energy spread - 1 sigma - before traversing the slab - can be 0 (array of size n).
