Vacuum Chamber, \(\beta^{+2}\) Particles And Dry Ice

 Helium nucleus at \(v_{boom}=0.3066\,ms^{-1}\),

\(He^2{\overset{\,\,\,v_{boom}\,\,\,}\longrightarrow}O^8\)

more elaborately,

\(He^2{\overset{\,\,\,v_{boom}\,\,\,}\longrightarrow}Be^4{\overset{\,\,\,v_{boom}\,\,\,}\longrightarrow}C^6{\overset{\,\,\,v_{boom}\,\,\,}\longrightarrow}O^8...\)

amongst the mess,

\(C+2O\to CO_2\)

carbon and oxygen combines to give dry ice.

A radioactive source of beta particles can readily achieve speed above the \(v_{boom}\) speed of \(0.3066\,ms^{-1}\) on exit.  The point is to observe helium nucleus at \(v_{boom}\) after being slowed by gravity.

Does the beta particles disintegrate, fuse and then two of the fusion products form into dry ice?  All fusion products, Beryllium, Carbon, Oxygen...should also be found.

This experiment would also indicate that fusion can be very very cold.
