Hi Jones,
I agree that Beryllium is an interesting possibility, but the reaction I would
expect is more like
Be9 + H => D + 2 x He4
No neutrino required.
or if you want to use D instead of H
Be9 + D => T + 2 x He4
However I think this might be less likely because the neutron capture cross
section of D is much lower than that of H
(IIRC).
The halo neutron might be easier to capture that one normally bound within a
nucleus. This is suggested by the fact that
Beryllium is used as a neutron multiplier.
