Another issue to consider is that the cross section of scattering is
much greater than that of fusion. Put another way, the ions are far
more likely to bounce off each other than fuse, even for head on
collisions. This is ok is magnetic confinement since each particle has
many "collisions" before it is likely to escape the system.
