Oops.  I checked.  There are fusion chains in which a proton decays to
give a neutron.  But the isotope reactions are a couple of orders
of magnitude more efficient, according to the ``Spaceflight Handbook''.
I also remember that the plans for BIS's Deadulus probe (to Barnard's Star)
called for fusion fuel pellets primarily of deuterium/tritium.  More
tomorrow (and hopefully some numbers).
