10.2} Partial pointwise transport with groupwise cross sections

 -------------------------

 For a few isotopes only, neutron transport can be done also using
 continuous (pointwise) cross sections. For 1H, 2H, 3He, 4He, and 12C,
 it is applied as a user option (above 3.05 eV for 1H, 2H, if requested 
 bound, at all energies for 3He, 4He, and 12C). For the reactions
 10B(n,alpha)7Li in 10B, and 14N(n,p)14C, the alpha and proton respectively
 are explicitly generated. 6Li pointwise treatment which was implemented
 in the past for the lowest part of the energy range is now no longer
 available, since a much more complete treatment can be requested
 using the full pointwise treatment (see paragraph 10.5).
