Fusion chain reaction?

Hi,

I was wondering what would happen if a roughly 10 MeV proton or
neutron was fired into a large dense target consisting of a mixture of
deuterium and tritium - let's say several cubic metres of gas held at
high pressure but low temperature so that it is almost at the density
of liquid water. I imagine that the target is large and dense enough
so that the projectile particle is guaranteed to scatter off a
deuterium or tritium atom rather than pass straight through the
target.


Would the high energy particle transfer enough kinetic energy to a
number of deuterium or tritium atoms so that they scatter with a high
kinetic energy and fuse with other deuterium/tritium atoms and thus
produce tritium, helium-3, helium-4 and further protons and neutrons
with varying kinetic energies?

Could one end up with a self-sustaining chain reaction occurring at a
relatively low temperature?

This would be different from the standard fusion schemes in which the
whole of the fuel is heated up to a temperature high enough to produce
fusion reactions.
